"Cei di wydraid o win coch. Ca i wydraid o win gwyn."

Translation: You will have a glass of red wine. I will have a glass of white wine.

[tachwedd]

But we were just taught that 'a glass of' is 'glasied' so I'm puzzled

[ibisc]

There are a couple of words in use for 'glassful', each with common variations:

• gwydraid (gwydred, gwydrad)
• glasiaid (glasied, glasiad)

Similarly, 'cupful':

• cwpanaid (paned, panad)
• dysglaid (disglad, disgled) (actually 'bowlful' but also used for cwpanaid in some dialects)
