'If you can cough any trifle on it up, Pip, I'd recommend you to do it' said Joe, all aghast. '(Manners is manners), but still your (elth's you elth)' A passage from Great Expectations by Charles Dickens.
I didn't get why the verb to be is in singular rather than plural in (Manners is manners)?
What does it mean the phrase or sentence 'elth's you elth'?
Thank you in advance. Emotion: smile
but still your health's your health

Representing (probably) a cockney pronunciation in which the "h" sound is dropped.

"Manners is manners" is portraying uneducated speech.

I recommend that you do not use brackets to highlight text in this way. It can be confusing.

Read the Dickens story out-loud together with an English coach to learn English pitch, inflection and intonation. The novel's grammar and word choice itself is obsolete! Like Shakespeare: 'Alas, poor Yorik, I knew him well'; or 'Lay on, MacDuff, and damned be he that first cries, 'Hold! Enough!'' Nobody talks that way anymore.

“Your elth’s your elth.” The context seems to indicate that “elth” is a shortening of “health”.
