"dy gath ddu ac oren di"

Translation: your black and orange cat

[Trine-]

Why is there a need for the di at the end?

[MrGWallCymraeg]

Shwmae! Sut dych chi? Sometimes the pronoun is run dy...di, eich...chi, ei...hi, fy...i and sometimes it's not - you'll hear both spoken.

Are both ways always correct? Is one more common than the other?

[shwmae]

In general terms:

"your cat"

eich cath = more formal

eich cath chi = pretty neutral

cath chi = more informal

"She sees you"

Mae hi'n eich gweld = more formal

Mae hi'n eich gweld chi = pretty neutral

Mae hi'n gweld chi = more informal

Thanks, now it makes much more sense!

[shwmae]

Yeah, it's overgeneralised but a good start. Croeso.
