Glove finally in hand of adult at party (6)
I believe the answer is:
fiesta
'party' is the definition.
(I've seen this before)
'glove finally in hand of adult' is the wordplay.
'finally' says to take the final letters.
'in' is an insertion indicator.
'hand of' becomes 'fist' (I can't explain this - if you can you should believe this answer much more).
'adult' becomes 'a' (abbreviation).
The final letter of 'glove' is 'e'.
'e' inserted inside 'fist' is 'fiest'.
'fiest'+'a'='FIESTA'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for fiesta that I've seen before include "celebration abroad" , "public event abroad" , "Elaborate public party, in Spain perhaps" , "A public holiday in Barcelona" , "Religious event" .)
