Words for resumes and cover letters
Hiring managers skim. Swap the vague phrase "ability to" for a stronger noun or a verb. Instead of ability to manage budgets, try proven competence in budget management, or better, managed a budget of 40,000 dollars. Use proficiency for tools and languages, expertise for a field you know deeply, and aptitude for things you pick up quickly.

Easy mistakes with ability words
Capacity can mean physical size, so "the team's capacity" may read as headcount rather than skill. Power can imply authority or force, which changes the meaning in a sentence about a student. Potential is about the future, not the present: a beginner has potential, an expert has skill. And gift sounds odd for ordinary work tasks; nobody has a gift for filing.
Antonyms for ability
The main opposite is inability, a neutral word for being unable. Incompetence is a harsh judgment of someone's work. Incapacity is formal and often legal or medical. Weakness is gentle and useful in interviews when you talk about areas to grow.
