Choose the most suitable option to replace the highlighted part of the sentence:
He is capable to do this work.
Show answer & explanation
Correct answer: A
Explanation
Answer: capable of doing
Corrected sentence: 'He is capable of doing this work.'
Rule applied:
The adjective 'capable' is always followed by the preposition 'of' + gerund (V-ing form) — never by 'to + verb (infinitive)'.
- ❌ capable to do
- ✅ capable of doing
Exam-speed trick: Certain adjectives always pair with 'of + V-ing', not 'to + V1':
- capable of doing
- incapable of doing
- fond of doing
- tired of doing
- afraid of doing (also can take 'to + V1' in some contexts, but 'of + V-ing' is standard)
- guilty of doing
Whenever you see 'capable to [verb]' in an error-spotting or sentence-improvement question, it's almost always a fixed trap — the answer will convert it to 'capable of + V-ing'.
