Throb with passion for hot bachelor (4)
I believe the answer is:
beat
'throb' is the definition.
(thesaurus)
'passion for hot bachelor' is the wordplay.
I cannot really understand how this works, but
'bachelor' could be 'b' (abbreviation e.g. BA=Bachelor of Arts) and 'b' is located in the answer.
The remaining letters 'eat' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'with' is the link.
Can you help me to learn more?
(Other definitions for beat that I've seen before include "Flog" , "cane" , "Overcome or hit repeatedly" , "Musical rhythm" , "Worst - best" .)
