It's lucky mother's got somewhere to put baby (6)
I believe the answer is:
mascot
'put baby' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'it's lucky mother's got somewhere' is the wordplay.
I cannot really see how this works, but
'mother's' could be 'mas' (Ma is another word for mother or mum) and 'mas' is found within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
The remaining letters 'co' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for mascot that I've seen before include "Lucky charm" , "Thing supposed to bring good luck" , "It's adopted by a team as a symbolic figure" , "Lucky talisman" , "It is believed to bring good luck to its owner(s)" .)
