Union seemingly leading to many a fine offspring? (7)
I believe the answer is:
liaison
'union' is the definition.
(I've seen this before)
'leading to many a fine offspring?' is the wordplay.
'leading' is a charade indicator (letters next to each other).
'to many a' becomes 'li' (I am not sure about this - if you are sure you should believe this answer much more).
'fine' becomes 'ai' (I've seen this in other clues).
'offspring?' becomes 'son' (son is a kind of offspring).
'li'+'ai' is 'liai'.
'liai'+'son'='LIAISON'
'seemingly' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for liaison that I've seen before include "Intimate relationship" , "Communication between organisations - or an illicit affair" , "Naughty affair?" , "Communication between people or organisations" , "Secret love affair" .)
