What's in a name? This for a start (7)
I believe the answer is:
initial
'for a start' is the definition.
(I have seen 'Start of name' mean 'initial' so perhaps 'start' could also mean 'initial')
'what's in a name?' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'this' acts as a link.
Can you help me to learn more?
(Other definitions for initial that I've seen before include "Let; rent" , "Endorse" , "write two or three letters, usually" , "First home, corgi, ultimately, wagging tail" , "Approve" .)
