C's mouth did not stop at all ...

I don't know whether there is an English idiom, in German it is: C's Mund wollte überhaupt nicht mehr aufhören, über S. zu reden.

Yes, sorry about that. Did not stop.

Dálach somebody comes from the name (Ó) Dálaigh
dá mbeifeá breoite ná faic mar sin dhíolfaidis thú here ná is used instead of nó because it is not mutually exclusive. Learners often compare ná to English 'nor' (which can only be used with negatives) and nó with 'or', but the truth is that ná can be used with positives and nó with negatives: aoinne a dhéanfaidh sraoth ná casachtach ná gáire ná osna ná é féin a thochas, beidh an trom trom air, and ní osclóidh mé an doras pé acu a thiocfaidh sé nó nach dtiocfaidh sé. Also, díol also means 'to pay' in Munster as well as 'to sell'
ceardchumann 'trade union'
ní dhiúltaíos di 'I didn't renounce/reject/resist her'

Molten - I'm familiar with the verbal adjective leachta. Ór leachta.

‘tigh’ = dative case here, I assume, not genitive = ‘in/at B’s ‘.

Tigh Bhridge could be in the functional genitive there if "Bridge's House tea" meant anything. What is tigh Bhridge? Does the context make it clear? If it's dative, then there would be an elided "ag" before it. But tigh is nominative and dative in Munster anyway.

Dative tigh (without a simple preposition) is used itself as a preposition, tigh X meaning "at X’s".
