If you are searching for synonyms representing “power”, likely you have one specific job in mind, therefore correct term depends solely upon that job. Discussing a president or a supervisor?

Below you will find eighteen (18) power synonyms listed by their meanings. Select the correct term according to your sentence, and it will guide you easily.

Quick Facts About “Power”

• Part of speech: mostly a noun; also a verb (the machine is powered by steam) and an adjective in compounds (power tool, power nap).
• Three core meanings: (1) control over people, (2) ability to do something, (3) physical strength or energy — including electricity.
• Register: neutral. Power works in essays, news, business, and everyday speech.
• Watch out: power is broader than any single synonym. That is exactly why swapping it blindly goes wrong.

The Closest Synonym Of Power: Authority

Authority is the closest synonym for power because it matches the meaning people reach for most often: the right to make decisions and have others follow them. When a mayor, a manager, or a court “has power,” what they really have is authority — power that comes from a position, a law, or an accepted role, not from physical strength.

Two differences still matter. First, authority is always legitimate power — it is granted, recognized, or written down somewhere. A robber has power over a victim for ten minutes, but nobody would call it authority. Second, authority usually names the right itself, while power can also name the force behind it. So “the manager has the authority to approve refunds” is precise, while “the manager has the power to approve refunds” is correct but slightly looser.

If your sentence is about who is allowed to decide, choose authority. If it is about who can actually make things happen — by strength, money, or personality — power or one of its other synonyms below will fit better.

Where “Power” Comes From (Etymology)

According to Etymonline, power entered English around 1300 as pouer, meaning “ability; ability to act or do; strength, vigor, might” and also “control, mastery, lordship, dominion, ability or right to command or control.” It came from Anglo-French pouair and Old French povoir — literally “to be able” — from Vulgar Latin potere, built on Latin potis, “powerful.”

That origin explains the word’s split personality today. From the very beginning, power meant both being able to do something and having command over others — and English never separated the two. The electricity sense arrived much later: “energy available for work” is recorded from 1727, and “electrical supply” only from 1896.

Can You Swap Them Freely?

Short answer: only inside the same meaning group. Power breaks into three separate jobs, and a synonym from one group will sound wrong in another:

• ✅ “The committee has the authority to reject the plan.” (control → control ✔)
• ❌ “The battery has a lot of authority.” (energy → control word ✘ — say power or capacity)
• ✅ “She has the ability to stay calm under pressure.” (ability → ability ✔)
• ❌ “He seized ability after the election.” (you seize power, control, or command — not ability)

Before you substitute, ask one question: is my sentence about ruling, doing, or forcing? Pick from that group and the swap will work.

Power Synonyms in Detail

Group 1 — Power Over People (Control and Authority)

1. Authority

• Meaning: The official or recognized right to make decisions, give orders, and enforce rules.
• Difference: Power that is granted and accepted. Authority comes from a position, a law, or expertise — never from brute force.
• Best used for: Governments, managers, courts, experts, official documents.
• Formality: Formal to neutral · CEFR: B2 · Frequency: Very common
• Example (Formal): “Only the head teacher has the authority to cancel classes.”
• Example (Everyday): “My team lead doesn’t have the authority to approve overtime.”
• When NOT to use it: For physical strength or electricity — a storm has no authority.

2. Control

• Meaning: The power to direct, manage, or restrain someone or something on an ongoing basis.
• Difference: Authority is the right; control is the actual steering. Control also works for things, not just people (control the temperature).
• Best used for: Managing systems, emotions, machines, situations.
• Formality: Neutral · CEFR: B1 · Frequency: Very common
• Example (Work): “She controls the entire marketing budget.”
• Example (Everyday): “He lost control of the car on the wet road.”
• When NOT to use it: When you mean the right to decide rather than the act of directing — that’s authority. (Compare how “coordination” differs from control: coordinating people is not the same as ruling them.)

3. Command

• Meaning: Authority that expects immediate obedience, especially in the military or in emergencies.
• Difference: Stronger and more one-directional than authority. A command is given, not discussed.
• Best used for: Armies, ships, emergency services, software instructions (a command).
• Formality: Formal · CEFR: B2 · Frequency: Common
• Example (Formal): “The general took command of the troops at dawn.”
• Example (Everyday): “Her command of Spanish impressed the whole panel.” (Note: command of a language = mastery — a fixed phrase.)
• When NOT to use it: In flat, democratic workplaces — it sounds too military.

4. Dominion

• Meaning: Complete, supreme rule over a territory or people.
• Difference: The heaviest word in this group — total ownership-like rule. Today it sounds historical, religious, or literary.
• Best used for: History, religion, fantasy writing, formal political theory.
• Formality: Very formal / literary · CEFR: C1 · Frequency: Rare in daily speech
• Example (Formal): “The empire held dominion over the coastal trade routes.”

• When NOT to use it: In modern business or school writing — control or authority will sound natural.

5. Sway

• Difference: Sway is soft power — people follow because they are persuaded or charmed, not because they must.
• Best used for: Politics, public opinion, persuasion. Almost always in the phrase hold sway (over).
• Formality: Neutral to formal · CEFR: C1 · Frequency: Uncommon
• Example (News): “The union leader holds considerable sway over the negotiations.”
• Example (Everyday): “Don’t let one bad review hold sway over your decision.”
• When NOT to use it: For official rights or physical force — sway is about minds, not muscles.

6. Influence

• Meaning: The power to affect how people think or act, indirectly and often gradually.
• Difference: Influence never commands. It shapes outcomes through respect, fame, money, or example.
• Best used for: Media, celebrities, parents, trends, marketing.
• Formality: Neutral · CEFR: B2 · Frequency: Very common
• Example (Work): “Her research had a huge influence on the new policy.”
• Example (Everyday): “Older brothers have more influence on him than any teacher.”
• When NOT to use it: When a direct order or legal right is meant — that’s authority or command.

7. Clout

• Meaning: Informal power to influence decisions, especially in politics and business.
• Difference: The street-level cousin of influence — clout is practical, behind-the-scenes pull, and the word itself is casual.
• Best used for: Politics, business deals, entertainment industry, journalism.
• Formality: Informal · CEFR: C1 · Frequency: Common in US media
• Example (News): “The senator has enough clout to block the bill.”
• Example (Everyday): “He used his clout to get his nephew an interview.”

Group 2 — Power to Do (Ability and Capacity)

8. Ability

• Meaning: The power or skill to do something; what a person is capable of doing.
• Difference: Ability lives inside a person. Power can come from outside (a position, a weapon); ability cannot be handed to you.

• Formality: Neutral · CEFR: B1 · Frequency: Very common
• Example (School): “The test measures your ability to solve problems quickly.”
• Example (Everyday): “She has an amazing ability to remember names.”
• When NOT to use it: For ruling others — a king’s power is not his “ability.” (See the detailed breakdown of “ability-type words” if skill is what you really mean.)

9. Capability

• Meaning: The ability to perform a specific task, often proven or measurable.
• Difference: More technical and task-focused than ability. Companies and machines have capabilities; people have abilities.

• Formality: Neutral to formal · CEFR: B2 · Frequency: Common
• Example (Everyday): “The hall has a seating capacity of 300.”
• Example (Work): “We’re working at full capacity this month.”
• When NOT to use it: For authority over people — nobody rules “by capacity.”

• Meaning: The ability to do something well enough — reliably and to an acceptable standard.
• Difference: Competence is ability with a quality bar attached. It says “good enough,” not “brilliant.”
• Best used for: Jobs, professional reviews, qualifications.
• Formality: Formal · CEFR: B2 · Frequency: Common
• Example (Work): “The audit raised questions about her competence as a manager.”
• Example (Formal): “Clinical competence is tested before doctors receive a license.”
• When NOT to use it: When you want praise — calling someone “competent” can sound like faint praise. For excellence, use expertise or mastery.

Group 3 — Power as Strength, Force, and Energy

12. Strength

• Meaning: The quality of being physically strong, or the degree of force/intensity of something.
• Difference: Strength is power you can measure in degrees — of a body, a drink, an argument, or a currency.
• Best used for: Bodies, materials, arguments, economies, signals.
• Formality: Neutral · CEFR: B1 · Frequency: Very common
• Example (Everyday): “He doesn’t have the strength to lift that box alone.”

• When NOT to use it: For official authority — laws have power/authority, not “strength.”

13. Force

• Meaning: Physical strength or violence used against something; in physics, a push or pull.
• Difference: Force is power in action, often aggressive. Police “use force”; nobody “uses authority” with their hands.
• Best used for: Physics, police/military action, storms, pressure.
• Formality: Neutral · CEFR: B2 · Frequency: Common
• Example (News): “Police used force to break up the fight.”
• Example (Science): “The force of gravity keeps the Moon in orbit.”
• When NOT to use it: For gentle influence — force always suggests pressure or violence.

14. Might

• Meaning: Great strength or power, especially of an army, a nation, or nature.
• Difference: Dramatic and literary. Might is the word of history books and speeches, not office emails.
• Best used for: Epic writing, history, rhetoric (military might, might and main).
• Formality: Formal / literary · CEFR: C1 · Frequency: Uncommon in speech
• Example (Formal): “The empire displayed its military might in the parade.”
• Example (Literary): “She pushed the door with all her might.”
• When NOT to use it: In casual modern prose — strength or power will sound natural.

15. Energy

• Meaning: The power that makes things work or move; also a person’s vitality and enthusiasm.
• Difference: Energy is power as fuel. For electricity specifically, energy is the scientific term; for people, it means liveliness, not authority.
• Best used for: Physics, electricity bills, health, personal productivity.
• Formality: Neutral · CEFR: B1 · Frequency: Very common
• Example (Science): “Solar panels convert sunlight into energy.”
• Example (Everyday): “After lunch I have zero energy for meetings.”
• When NOT to use it: For decision-making authority — a CEO’s power is not “energy.”

16. Potency

• Meaning: The power of something to produce an effect — especially medicine, drink, or an argument.
• Difference: Potency is power per dose. A potent drug is strong in small amounts.
• Best used for: Medicine, chemistry, persuasive writing/speech.

• Example (Everyday): “Grandpa still gardens with the vigor of a young man.”
• When NOT to use it: For legal or political authority.

18. Electricity

• Meaning: The form of energy carried by electric current — the thing itself, where power is the supply of it.
• Difference: In the blackout sense the two swap cleanly (“the electricity/power went out”). But electricity names the energy form, while power also covers its rate and supply.
• Best used for: Homes, bills, outages, appliances.
• Formality: Neutral · CEFR: B1 · Frequency: Very common
• Example (Everyday): “The electricity went out during the thunderstorm.”
• Example (Work): “The factory’s electricity bill doubled this winter.”
• When NOT to use it: In physics formulas (there, power is a precise term: energy per second) or for any human authority.

Words Commonly Confused With “Power”

These words show up next to power in thesauruses, but they fail the swap test. Use them carefully:

• Powerful — This is the adjective form (“a powerful leader,” “a powerful engine”). It describes someone or something that has power; it can never replace the noun. “She has powerful” is simply broken English.
• Empowerment — The process of giving power to people who lacked it. A company can run an empowerment program, but a president does not “hold empowerment” — he holds power.
• Superpower — A fictional or extraordinary ability (flight, invisibility), or in politics, a dominant nation like the US or China. It is not a general synonym; your manager does not have superpowers, however impressive she is.
• Willpower — Self-control only: the power to resist temptation and stick to decisions. It belongs to the ability family but covers just one narrow corner of it.
• Power of attorney — A legal document that lets one person act for another. Here power means a specific legal right, and no synonym fits — never rewrite this phrase.

Best Alternatives by Context

Real situations, real fixes — find the one closest to yours:

You’re writing about an election or a government. “The party came into power” is already perfect. For the right to govern, write authority; for day-to-day steering of the country, control; for a ruler who answers to nobody, dominion (formal) fits history essays.

You’re describing a manager at work. A good manager rarely has “power” in good writing — she has authority (the right to decide), influence (people listen to her), or, if everyone fears crossing her, clout. Notice how each choice changes what you’re really saying.

You’re writing a school or job essay about skills. Drop power completely. “The power to communicate well” sounds inflated; “the ability to communicate well” is natural, and “capability” or “competence” sounds more professional. This is also where “teamwork” essays go wrong — teams succeed through ability and coordination, not “power.”

You’re describing a storm, an engine, or a weightlifter. Use strength for how powerful something is, force for the push itself, and might only if you’re writing something dramatic or historical.

The lights just went out. Say “the power went out” (AmE) or “the electricity went out” — both natural. On the bill and in the science lesson, prefer electricity or energy.

FAQ

What is the closest synonym for power?

Authority is the closest synonym when power means control over people and decisions, because it names the same thing — the recognized right to decide and be obeyed. It does not cover the other meanings, though: for ability, use ability or capability, and for physical force, use strength or force.

What is another word for power in electricity?

Electricity and energy are the two natural alternatives. Say “the electricity went out” for a blackout, and use energy in science and industry contexts, as in “wind energy.” In technical writing, though, power is a precise measurement (energy per second, in watts), so there it should not be replaced at all.

Is “powerful” a synonym for power?

No. Powerful is an adjective that describes someone or something possessing power, while power is the noun itself. You can write “a powerful engine” or “the engine has power,” but powerful can never take the noun’s place in a sentence, which is why it belongs with commonly confused words, not synonyms.

What is the difference between power and authority?

Authority is power that is legitimate and recognized — granted by a law, a job, or expertise. Power is the wider word: it can be legitimate or not, and it can also mean physical strength or energy. A kidnapper has power over a victim but no authority; a judge has both.

What is a stronger word than power?

For control, dominion and command sound stronger and heavier than power. For influence, clout suggests real behind-the-scenes weight, while for physical force, might is the most dramatic choice. Stronger is not always better, though — in everyday writing these words can sound exaggerated, so save them for formal or literary contexts.

What is the opposite of power?

It depends on the meaning. The opposite of power as control is powerlessness, subordination, or submission. The opposite of power as ability or strength is weakness, inability, or incapacity. English has no single antonym because power itself covers several meanings, and each meaning has its own natural opposite.

Conclusion

Power is really three words wearing one coat — ruling people, being able to do something, and raw strength or energy — and every synonym in this guide belongs to just one of those families.

Match the family first, then fine-tune for formality: authority for the official right, influence for the quiet kind, capability for the provable kind, force for the physical kind.

Do that, and you’ll never write a sentence where a battery has authority or a king has “ability” again. When in doubt, keep power itself — it is a strong, natural word — and reach for a synonym only when it says something power doesn’t.
