Woman finds the queen transparent (5)
I believe the answer is:
sheer
'transparent' is the definition.
(synonyms)
'woman finds the queen' is the wordplay.
'woman' becomes 'she' ().
'finds' means one lot of letters go next to another.
'the queen' becomes 'ER' (Elizabeth Regina ie Queen Elizabeth).
'she'+'er'='SHEER'
(Other definitions for sheer that I've seen before include "Absolute - precipitous" , "(Of fabric) very thin" , "sudden change of direction" , "Precipitous or fine" , "Very thin; unmitigated" .)
