Woman's essay has editor bemused (10)
I believe the answer is:
distracted
'bemused' is the definition.
(distracting is a kind of bemusing)
'woman's essay has editor' is the wordplay.
'woman's' becomes 'dis' (Di is short for Diana).
'essay' becomes 'tract'.
'has' says to put letters next to each other.
'editor' becomes 'ed'.
'dis'+'tract'+'ed'='DISTRACTED'
(Other definitions for distracted that I've seen before include "Troubled - ID card test (anag)" , "Preoccupied" , "Diverted (attention) from (something)" .)
