Artificial plaits blown around (7)
I believe the answer is:
plastic
'artificial' is the definition.
(I've seen this in another clue)
'plaits blown around' is the wordplay.
'blown' is an anagram indicator (to blow can mean to disrupt or scatter).
'around' becomes 'c' (abbreviation for 'circa').
'plaits' anagrammed gives 'plasti'.
'plasti'+'c'='PLASTIC'
(Other definitions for plastic that I've seen before include "Euphemism for a credit card" , "Like some cards" , "Credit cards are known as ....... money" , "Clasp it (anag.)" , "Mouldable material" .)
