Stream of abuse? Or rising support for one of those in Galway! (8)
I believe the answer is:
diatribe
'stream of abuse?' is the definition.
(I've seen this before)
'rising support for one of those in galway' is the wordplay.
I cannot really understand how this works, but
'support' could be 'rib' (rib is a kind of support) and 'rib' is found within the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
The remaining letters 'date' 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).
'or' is the link.
Can you help me to learn more?
(Other definitions for diatribe that I've seen before include "Hostile rant" , "Loud verbal attack" , "Bitter verbal attack" , "provoking verbal onslaught" , "Lengthy harangue" .)
