in Ireland, us is sounded huz, which might seem a Cockney vulgarism, but I think it is not. In Roscommon and in the Munster counties a thong is called a fong.
Chaw for chew, oncet [wonst] for once, twiced for twice, and heighth, sighth, for height, sight, which are common in Ireland, are all old English survivals. Thus in the 'Faerie Queene' (Bk. I., Canto IV., XXX.):—
'And next to him malicious Envy rode
Upon a ravenous wolfe and still did chaw
Between his cankred teeth a venomous tode.'
Chaw is also much used in America. 'Onst for once, is in the Chester Plays' (Lowell); and highth for height is found all through 'Paradise Lost.' So also we have drooth for drought:—
'Like other historians I'll stick to the truth
While I sing of the monarch who died of the drooth.'
(Sam Lover.)
Joist is sounded joice in Limerick; and catch is everywhere pronounced ketch.
