"Is someone there?"
Translation:Oes rhywun yno?
January 12, 2017
As EllisV has said, Oes...? is the question word for the existence of indefinite things:
- Oes teigr yn yr ardd? is asking about the possible existence of any old tiger in the garden.
- Ydy Tim y teigr yn yr ardd? is asking about the presence of a specific, identified tiger called Tim in the garden.
