These to hand, not just for children (3,6)
I believe the answer is:
kid gloves
'these' is the definition.
The definition suggests an adverb but the answer is not.
'hand not just for children' is the wordplay.
I cannot quite understand how this works, but
'hand' could be 'glove' and 'glove' is found within the answer.
'children' could be 'kids' ('kid' can be a synonym of 'child') and 'kids' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for kid gloves that I've seen before include "essential wear for diplomats?" , "Leather hand coverings" .)
