Caught greeting worker - one supplying wine (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'caught greeting worker one' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'greeting' becomes 'hi' (hi is a kind of greeting).
'worker' becomes 'ant' (worker is a type of ant).
'one' becomes 'i' (Roman numeral).
'c'+'hi'+'ant'+'i'='CHIANTI'
'supplying' acts as a link.
(Other definitions for chianti that I've seen before include "Tuscan red wine" , "Popular dry red wine of Tuscany" , "European wine" , "I can hit for popular Italian wine" , "Chain it to popular Italian wine" .)
