Original part of name (7)
I believe the answer is:
initial
'original' is the definition.
(I've seen this before)
'part of name' is the wordplay.
I cannot really see how this works, but
'part' could be 'ti' (ti is a kind of part) and 'ti' is found within the answer.
'name' could be 'al' and 'al' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for initial that I've seen before include "Start of name" , "First home, corgi, ultimately, wagging tail" , "Approve" , "Occurring at the beginning" , "Name's first letter" .)
