A woman in Batavia (3)
I believe the answer is:
ava
This clue might be a double definition.
'a woman' is the first definition.
'batavia' is the second definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I can't see?
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ava that I've seen before include "- - Gardner (films)" , ". . . Gardner (film star)" , "-- Gardner, US actress" , "woman" , "girl" .)
