"Dw i eisiau dy feiro di."

Translation: I want your biro.

[JeffA2]

What on earth is a biro?

[Mwsogl]

It's from the inventor, László Bíró who invented the ballpoint pen. In British English it became the generic term for a ballpoint pen. Actually the picture that was shown when the word was introduced was a fountain pen, so that may be adding to the confusion. That would be a "ysgrifbin" or just "pen" and a ballpoint pen is a "beiro".

[JeffA2]

Thanks for the information. I must have tested out of the section where it was introduced, or I probably would have recognized it when it came up again.

All that comes for me is an obscure name for ballpoint pen.

[areddragon]

It's a pretty common name for ballpoint pens in schools in Wales, at least, to be fair.

[shwmae]

Yeah, in UK English I'd say. We use it to just mean "pen" a lot of the time in Welsh too.

[JeffA2]

Yeah, I guess that must be it. Google was not actually very helpful on this one. Since it was introduced in "Family" I thought it must be some slangy name for some form of relative, but probably not.

[posthuman01]

It's cool our german and welsh stats are almost the same. Spanish is actually pretty close too.

[romankiw]

Same issue here. I'm American, and had no idea what a "biro" was.
