Competent student’s hugged by Abraham (4)
I believe the answer is:
'competent' is the definition.
(similar in meaning)
'student's hugged by abraham' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'hugged by' indicates putting letters inside (I've seen this in other clues).
'abraham' becomes 'abe'.
'l' inserted inside 'abe' is 'ABLE'.
(Other definitions for able that I've seen before include "Having the necessary capacity (to do something)" , "Adept" , "See 10" , "Competent and equipped" , "Capable or proficient" .)
