Capricorn possibly subject about ram's head? (6)
I believe the answer is:
tropic
'capricorn' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'subject about ram's head?' is the wordplay.
'subject' becomes 'topic' (as in a topic for discussion).
'about' indicates putting letters inside.
'head?' suggests taking the first letters (I've seen 'heads of' mean this).
The initial letter of 'rams' is 'r'.
'topic' placed around 'r' is 'TROPIC'.
'possibly' is the link.
Can you help me to learn more?
(Other definitions for tropic that I've seen before include "Cancer/Capricorn line" , "Latitude associated with Capricorn or Cancer" , "One of two lines" , "Parallel of latitude about 25o N or S" , "Interzonal line" .)
