用法パターン：
[someone] is incompetent at [doing something]; an incompetent [worker/doctor/manager]
よくある間違い：
Learners sometimes confuse "incompetent" with "incomplete". "Incompetent" describes a person or performance that is not good enough. "Incomplete" describes something that is not finished or not whole. Learners may also overuse "very incompetent"; in natural English, speakers more often say "totally incompetent" or "completely incompetent".
