"Pwy dych chi?"

Translation: Who are you?

[Grace677542]

What would the difference be between "Pwy dych chi" and "Pwy wyt ti" ?

[rmcode]

'Pwy dych chi' ('dach chi' in NW) is the formal or plural form of 'Who are you?"

'Pwy wyt ti' is the informal singular form.

[DuoUnderscore]

Would you use the informal when talking to children? I can't imagine any other scenario one would be comfortable enough to speak informally to another who they don't yet know.

Is there a cultural thing? When would I use each?

[ibisc]

This is explained in the course notes. In short:

• ti is only used with an individual with whom you are on familiar terms. It would also be used with a child.
• chi is used with any two or more people, and with an individual with whom you are not on familiar terms.

Diolch!
