High-flying team lets Ronald join at last. (8)
I believe the answer is:
squadron
'high-flying team' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe there's a link between them I don't understand?
'ronald join at last' is the wordplay.
'ronald' becomes 'ron' (I've seen this in other clues).
'join' says to put letters next to each other.
'at last' becomes 'squad' (I can't justify this - if you can you should give a lot more credence to this answer).
'ron' put after 'squad' is 'SQUADRON'.
'lets' is the link.
Can you help me to learn more?
(Other definitions for squadron that I've seen before include "Military unit" , "Air force grouping" , "Cavalry unit" , "detachment" , "several planes" .)
