Ability is the correct spelling. Abillity is incorrect.
Use ability when you mean skill, talent, power, or the capacity to do something.
Correct: She has the ability to solve problems quickly.
Incorrect: She has the abillity to solve problems quickly.
There is no standard English situation where abillity is preferred. It is simply a misspelling with one extra l.
Ability vs Abillity At A Glance
| Word | Correct? | Meaning | Should You Use It? |
|---|---|---|---|
| Ability | Yes | Skill, talent, power, or capacity | Yes |
| Abillity | No | No standard meaning | No |
The difference is not about tone, grammar style, or American vs. British English. The difference is simple: ability is the standard spelling, and abillity is a spelling mistake.
What Ability Means
Ability is a noun. It means the skill, power, talent, or capacity to do something.
You can use ability when talking about mental skills, physical skills, work skills, natural talent, learned skills, or practical power.
Examples:
- Her ability to explain hard ideas makes her a great teacher.
- The job requires strong writing ability.
- His athletic ability helped the team win.
- The app gives users the ability to edit files offline.
- Good leaders need the ability to listen carefully.
- The student showed the ability to learn from feedback.
- Her problem-solving ability helped the company avoid delays.
In simple terms, ability means what someone or something can do.
Why Abillity Is Wrong
Abillity is wrong because the correct spelling has only one l.
Correct: ability
Incorrect: abillity
Many people add an extra l because the middle of ability sounds like “bill.” That sound can make the word feel like it should be spelled with two l letters.
But English spelling does not always match sound perfectly. Even though you hear a “bill” sound, the written word is still ability.
The extra l in abillity makes the word incorrect.
How To Pronounce Ability
Ability is usually pronounced:
uh-BIL-uh-tee
The stress is on the second syllable: BIL.
That stressed “bil” sound is one reason writers sometimes type abillity by mistake. The sound may seem strong, but the spelling still uses only one l.
Correct spelling: ability
Incorrect spelling: abillity
The Best Memory Trick
The easiest way to remember the spelling is:
Able has one “l,” so ability has one “l.”
Think of the word this way:
able → ability
Not:
able → abillity
The root word able already has one l. When it becomes ability, it keeps that same one-l pattern.
Another quick reminder:
- ability = correct
- abillity = too many l letters
When To Use Ability
Use ability whenever you mean skill, power, talent, or capacity.
You can use it in:
- school essays
- homework
- resumes
- cover letters
- business emails
- reports
- social media posts
- personal writing
- website copy
- professional bios
Examples:
- The student showed strong reading ability.
- I admire your ability to stay calm under pressure.
- The role requires the ability to manage several projects.
- Her leadership ability helped the team finish on time.
- The software gives customers the ability to control their settings.
- His musical ability developed at a young age.
- The course helps improve public speaking ability.
In every example above, ability is the right spelling.
Ability In School Writing
Students often use ability when writing about learning, skills, performance, and improvement.
Correct:
- The test measured each student’s reading ability.
- Practice can improve your writing ability.
- Her ability to understand science improved during the semester.
- The teacher noticed his ability to solve math problems quickly.
Incorrect:
- The test measured each student’s reading abillity.
- Practice can improve your writing abillity.
In school writing, spelling mistakes can lower the quality of an otherwise strong answer. If you are writing an essay, assignment, or exam response, always use ability.
Ability In Professional Writing
Spelling matters even more in professional writing. A small mistake can make a resume, email, or report look rushed.
Resume example:
Correct: Proven ability to train new employees.
Incorrect: Proven abillity to train new employees.
Email example:
Correct: I appreciate your ability to respond quickly.
Incorrect: I appreciate your abillity to respond quickly.
Report example:
Correct: The new system improves our ability to track orders.
Incorrect: The new system improves our abillity to track orders.
Cover letter example:
Correct: My ability to manage deadlines makes me a strong fit for this role.
Incorrect: My abillity to manage deadlines makes me a strong fit for this role.
If the writing is important, proofread for this mistake before sending it.
