A sharp funny line in a few words (7)

Ross

I believe the answer is:

phrasal

'in a few words' is the definition.
(in a phrase)

'a sharp funny line' is the wordplay.
'funny' indicates anagramming the letters.
'line' becomes 'l' (used when specifying particular lines from a poem).
'a'+'sharp'='asharp'
'asharp' with letters rearranged gives 'phrasa'.
'phrasa'+'l'='PHRASAL'

I've seen this clue in The Guardian.
