How do you say nothing in Welsh?

There are a few ways to say "nothing" in Welsh, depending on the context:

* Dim byd: This is the most common and literal translation, meaning "no thing." It's a versatile phrase that can be used in most situations.

* Dim ond: This translates to "only nothing" and can be used to emphasize that there is absolutely nothing. For example, "Dim ond yn y fan hyn" means "Only nothing is here."

* Dim: This is a shorter version of "dim byd" and simply means "no." It can be used in situations where "nothing" is understood from the context.

* Nid oes dim: This literally means "there is not nothing." This is a more formal way of saying "nothing" and is often used in written texts.

The best choice depends on the specific context and desired emphasis.
