An entertaining lady (7)
I believe the answer is:
hostess
'an entertaining lady' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'lady' is the wordplay.
I cannot really understand how this works, but
'lady' could be 'tess' (I've seen this before) and 'tess' is found in the answer.
The remaining letters 'hos' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hostess that I've seen before include "She looks after guests" , "She entertains guests" , "who welcomes guests?" , "party organiser" , "Woman employed by a nightclub" .)
