Breezy if one's collected by helicopter dropping over (7)
I believe the answer is:
chipper
'breezy' is the definition.
(thesaurus)
'one's collected by helicopter dropping over' is the wordplay.
I cannot really see how this works, but
'by' could be 'per' (I've seen this in another clue) and 'per' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'if' is the link.
Can you help me to learn more?
(Other definitions for chipper that I've seen before include "person damaging crockery?" , "stonemason?" , "type involved in 6 [CARPENTERING] ?" , "Briskly cheerful" , "Debonair" .)
