Adaptable, the Spanish clubs stocking Italian wine (7)
I believe the answer is:
elastic
'adaptable' is the definition.
(similar in meaning)
'the spanish clubs stocking italian wine' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'clubs' becomes 'c' (abbreviation in card games).
'stocking' means one lot of letters goes inside another ('stock' can mean 'carry' or 'contain').
'italian wine' becomes 'asti' (Asti is a type of Italian wine).
'el'+'c'='elc'
'elc' enclosing 'asti' is 'ELASTIC'.
(Other definitions for elastic that I've seen before include "'Flexible, springy (7)'" , "Flexible, adaptable" , "Cats lie (anag.)" , "Scale it (anag.)" , "Material that stretches" .)
