Aphrodite took him to her heart (3)
I believe the answer is:
rod
'him to her heart' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'aphrodite took' is the wordplay.
'took' indicates a hidden word (I've seen 'taking' mean this (the answer is carried or taken by the clue)).
'ROD' can be found hidden inside 'aphrodite'.
Can you help me to learn more?
(Other definitions for rod that I've seen before include "Long, straight stick" , "Imperial measure" , "Stick; angler" , "Rigid stick" , "- - , pole or perch" .)
