I would like to know what "Hoo's fully resolved t' sew up meawth an' eend" means in the following stanza:
Eawr Marget declares had hoo cloo'as to put on,
Hoo'd goo up to Lunnon an' talk to th' greet mon;
An' if things were na awtered when there hoo had been,
Hoo's fully resolved t' sew up meawth an' eend;
Hoo's neawt to say again t' king,
But hoo loikes a fair thing,
An' hoo says hoo can tell when hoo's hurt.
In this novel which is published in 1848 in the United Kingdom, Alice hosted a tea party at her own house, to which Mary and Margaret were invited. During the party, Alice asked Margaret, a very good singer, to sing "The Oldham Weaver." At this request, Margaret began to sing this Lancashire ditty.
(This song is about a very poor cotton weaver, who lives with his daughter Margaret (or Marget). They are very poor so that they have nothing to eat, and they are being driven to starvation. That is why Margaret is determined to go to London to see "the great man" to explain their circumstances.)
In this part, I could not understand what the stanza in bold means.
