Celebration that's in the way (6,5)
I believe the answer is:
street party
'celebration' is the definition.
(I know that street party is a type of celebration)
'in the way' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'way' could be 's' (Compass direction - South) and 's' is found within the answer.
This explanation may well be incorrect...
'that's' is the link.
Can you help me to learn more?
(Another definition for street party that I've seen is " Communal urban celebration".)
