Mae rhai'n hoff o ddyfynnu'r ddihareb:
- Paid â chodi pais ar ôl piso - don't cry over spilt milk
Heblaw am hynny, dw i wedi dod o hyd i 'pais' (fel petticoat?) rywle yn straeon 'Te yn y Grug' gan Kate Roberts - rhywbeth ynglŷn â pharatoi dillad i Wini Ffini cyn iddi fynd i weithio yn y dre, efallai?
First I didn't know that underskirt was pais in Welsh so I just wrote G to get it wrong than it said it was pais so I memorised it and later when it asked me the same question kablam I got it correct now I know what underskirt is in Welsh but maybe I'll forget it in the future so i'll revise it. C u l8ter.
