Fry rank chicken? (7)
I believe the answer is:
stephen
'fry' is the definition.
(I've seen this before)
'rank chicken?' is the wordplay.
'rank' becomes 'step' (step is a kind of rank).
'chicken?' becomes 'hen' (hen is a kind of chicken).
'step'+'hen'='STEPHEN'
(Other definitions for stephen that I've seen before include "English king from eleven hundred and thirty five" , "Old king" , "Chap" , "-- Hawking, English physicist" , "Boxing day is St -'s day" .)
