A silk handkerchief to make dirty at a garden centre (7)
I believe the answer is:
foulard
'a silk handkerchief' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'dirty at a garden centre' is the wordplay.
'dirty' becomes 'foul' (synonyms).
'at' means one lot of letters go next to another.
'centre' means to look at the middle letters.
The middle of 'garden' is 'rd'.
'foul'+'a'+'rd'='FOULARD'
'to make' is the link.
Can you help me to learn more?
(Other definitions for foulard that I've seen before include "A scarf" , "tie" , "Material" .)
