Tightwad from Welsh town discovered begging previously (9)
I believe the answer is:
skinflint
'tightwad' is the definition.
(synonyms)
'welsh town discovered begging previously' is the wordplay.
'welsh town' becomes 'flint' (I've seen this before).
'discovered' says to take the centre.
'begging' becomes 'asking' (I've seen this before).
'previously' means one lot of letters go next to another.
The middle of 'asking' is 'skin'.
'flint' after 'skin' is 'SKINFLINT'.
'from' acts as a link.
(Other definitions for skinflint that I've seen before include "Scrooge, miser" , "cheapskate" , "A mean, miserly person" , "Very ungenerous or stingy person" , "A miserly person, tightwad" .)
