できるCan do / able to
Expresses ability or possibility. Noun + が + できる means 'can do (noun)' or '(noun) is possible.' Also used to mean 'to be completed/ready.' The object of ability takes が, not を.
Common mistakes
- Using を instead of が — the thing one can do takes が with できる
- Confusing できる (ability) with する (to do) — できる implies capability, not just action
