Member of nobility considers swallowing tablets (8)
I believe the answer is:
countess
'member of nobility' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'considers swallowing tablets' is the wordplay.
'considers' becomes 'counts' ('count' can be a synonym of 'consider').
'swallowing' indicates putting letters inside.
'tablets' becomes 'es' (E can refer to an ecstasy tablet).
'counts' enclosing 'es' is 'COUNTESS'.
Can you help me to learn more?
(Other definitions for countess that I've seen before include "title for 23 [LOVELACE]" , "Aristocratic partner" , "Titled lady" , "Noble" , "Earl's wife" .)
