Covering victory in Europe - born by Romanian capital (6)
I believe the answer is:
veneer
'covering' is the definition.
(I know that veneer is a type of covering)
'victory in europe born by romanian capital' is the wordplay.
'victory in europe' becomes 'VE' (abbreviation as in 'VE Day').
'born' becomes 'nee' ('nee' is 'born' in French).
'by' is a charade indicator (letters next to each other).
'capital' says to take the initial letters.
The first letter of 'romanian' is 'r'.
've'+'nee'+'r'='VENEER'
(Other definitions for veneer that I've seen before include "Thin decorative covering of fine wood" , "Thin coating on the outside" , "A thin layer on the surface, often wood" , "Decorative surface layer" , "Thin layer of wood or plastic" .)
