Female of the week? (3)
I believe the answer is:
ewe
'female' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'of the week?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'EWE' is hidden in the letters of 'the week'.
Can you help me to learn more?
(Other definitions for ewe that I've seen before include "21a [SHEEP]" , "The sort of beast" , "Female animal" , "Lamb supplier" , "Scottish loch" .)
