Q11
EnglishVocabulary: Meaning, Synonyms & Antonyms
Add a suitable prefix to form the opposite of the word 'capable'.
  1. a.Uncapable
  2. b.Noncapable
  3. c.Ill-capable
  4. d.Incapable

Answer: (D) Incapable

The correct negative of 'capable' is 'incapable', formed with the Latin prefix in- ('not'); 'uncapable', 'noncapable' and 'ill-capable' are not standard forms. Note the trap that the related word 'able' takes un- ('unable'), while its nouns take in- or dis- ('inability', 'disability'). The prefix in- becomes im- before b/m/p (impossible), il- before l (illegal) and ir- before r (irregular).
