Heartless male student in contact with head (5)
I believe the answer is:
melon
'head' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'heartless male student in contact with' is the wordplay.
'heartless' suggests removing the centre.
'student' becomes 'l' (as in L-plates for learner drivers).
'in contact with' becomes 'on' (to be on something is to be touching it).
'male' with its middle removed is 'me'.
'me'+'l'+'on'='MELON'
Can you help me to learn more?
(Other definitions for melon that I've seen before include "Killing" , "Large sweet gourd" , "Sweet juicy gourd" , "Member of the gourd family" , "Cantaloupe fruit" .)
