Woman is on father's land (6)
I believe the answer is:
pampas
'land' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'woman is on father's' is the wordplay.
'woman' becomes 'pam' ().
'is on' says to put letters next to each other (in a down clue, letters appear on others).
'father's' becomes 'pa's' (pa can mean dad or father).
'pam'+'pas'='PAMPAS'
Can you help me to learn more?
(Other definitions for pampas that I've seen before include "South American plains" , "South American grassland" , "Plains with grass" , "Argentinian plains" , "Vast plains of South America" .)
