"Dych chi'n gwerthu dillad ysgol yma?"

Translation: Do you sell school clothes here?

[samcrawford]

"Do you sell school uniforms here?" should be accepted

[tu.8zPhLD72zzoZN]

School uniforms are school clothes, but school clothes are not necessarily school uniforms. Not all schools require uniforms. '
"gwysg ysgol" = "school uniforms"

[serenlicht]

Why is it Chi'n and not Chi?

[Sarah-Cheung]

According to what I have learned so far, "yn" is there to introduce the verb "gwerthu". And because it follows "chi", "y" gets omitted and they become "chi'n".

[RowenaJane]

I only know 'dach chi'----
