Tarzan's sweetheart for one short month? (4)
I believe the answer is:
jane
'tarzan's' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'sweetheart for one short month?' is the wordplay.
'sweetheart' becomes 'e' (the middle letter or heart of 'sweet').
'for' means one lot of letters go next to another (I've seen this in other clues).
'one short month?' becomes 'jan' (Jan is short for January; 'short' asks for a short form).
'e' put after 'jan' is 'JANE'.
Can you help me to learn more?
(Other definitions for jane that I've seen before include "English novelist" , "See 1" , "accepts her" , "Tarzan's girl" , "swinger's partner, perhaps" .)
