Bride's attendant holding donkey with a yoke heading to aisle (10)
I believe the answer is:
passageway
'aisle' is the definition.
(thesaurus)
'bride's attendant holding donkey with a yoke heading' is the wordplay.
'bride's attendant' becomes 'page' (as in a page boy).
'holding' indicates putting letters inside.
'donkey' becomes 'ass' (ass is a term for a donkey).
'with' becomes 'w' (abbreviation).
'heading' indicates taking the first letters (head could mean the top letter).
The first letter of 'yoke' is 'y'.
'page' going around 'ass' is 'passage'.
'passage'+'w'+'a'+'y'='PASSAGEWAY'
'to' is the link.
(Other definitions for passageway that I've seen before include "Corridor" , "Alley" .)
