Again prevail upon to go round and say hello to (5)
I believe the answer is:
greet
'say hello to' is the definition.
(I've seen this in another clue)
'again prevail upon to go round' is the wordplay.
I cannot quite understand how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is located in the answer.
'go' could be 'get' (synonyms) and 'get' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for greet that I've seen before include "Make welcome" , "Welcome; cry (Scots)" , "Receive (someone)" , "Welcome (someone)" , "Receive - salute" .)
