The woman finds queen transparent (5)
I believe the answer is:
sheer
'transparent' is the definition.
('sheer' can be a synonym of 'transparent')
'the woman finds queen' is the wordplay.
'the woman' becomes 'she' (I've seen this before**).
'finds' means one lot of letters go next to another.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'she'+'er'='SHEER'
(Other definitions for sheer that I've seen before include "Film" , "Deviate (from) - vertical" , "Very fine like silk stockings" , "needing to change a course" , "sudden change of direction" .)
