"Chi sy'n casglu stampiau."

Translation: It is you who collects stamps.

[Nige101265]

"it is you who collects stamps" is a very literal translation. wouldn't "you collect stamps" be more 'normal' english?

[ibisc]

Yes, and that is accepted. The 'It is you who...' is just a way of translating the emphatic sense of Chi sy'n....

The emphatic construction is much more usual in Welsh than in English.
