Match official with gear (ecstasy, speed) to chill (11)
I believe the answer is:
refrigerate
'chill' is the definition.
(refrigerating is a kind of chilling)
'match official with gear ecstasy speed' is the wordplay.
I cannot really understand how this works, but
'official' could be 'ref' (match official in football, say) and 'ref' is located in the answer.
an anagram of 'gear' is 'gera' which is located in the answer.
'ecstasy' could be 'e' (informal term for the drug) and 'e' is present in the answer.
The remaining letters 'rit' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for refrigerate that I've seen before include "Keep (food or drink) cold" , "Cool!" , "Chill" , "Provide cooling" , "Freeze" .)
