Female teacher in design (9)
I believe the answer is:
catherine
'female' is the definition.
(I've seen this before)
'teacher in design' is the wordplay.
'design' is an anagram indicator.
'teacher'+'in'='teacherin'
'teacherin' with letters rearranged gives 'CATHERINE'.
(Other definitions for catherine that I've seen before include "Parr or Howard, say" , "Name of three wives of Henry VIII" , "woman" , "-- Wheel; -- the Great" , "-- Parr; -- wheel" .)
