Panache lacking at the start in eyesore? (5)
I believe the answer is:
style
'panache' is the definition.
(I know that panache can be written as style)
'lacking at the start in eyesore?' is the wordplay.
'at the start' suggests taking the first letters.
'in' means one lot of letters goes inside another.
'eyesore?' becomes 'stye' (I've seen this before).
The first letter of 'lacking' is 'l'.
'l' put into 'stye' is 'STYLE'.
(Other definitions for style that I've seen before include "Designate" , "Former writer" , "Fashion, manner, mode" , "Method; elegance" , "Chic" .)
