"Dau lasied bach"

Translation: Two small glassfuls

[AbunPang]

I have two questions:

1. What’s the singular form of what I guess is glasied in unmutated form?
2. Is there a difference between this word an gwydraid?

[ibisc]

glasied/glasiaid is the singular - singular nouns are used after numbers in this pattern.

It has the same meaning as gwydraid.

Thanks!
