Light-coloured tie worn by large European (6)
I believe the answer is:
blonde
'light-coloured' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'tie worn by large european' is the wordplay.
'tie' becomes 'bond' (bonding is a kind of tiing).
'worn by' indicates putting letters inside (outside letters are worn by those on the inside).
'large' becomes 'L' (eg in clothes sizes).
'european' becomes 'E' (abbreviation e.g. EU).
'bond' enclosing 'l' is 'blond'.
'blond'+'e'='BLONDE'
Can you help me to learn more?
(Other definitions for blonde that I've seen before include "Flaxen" , "Fair lady" , "Of a woman, having fair hair (6)" , "Kind of fair girl" , "Fair-headed" .)
