Ar lafar, fyddwn ni ddim yn defnyddio 'mae'n' fel arfer.
Er mwyn gofyn cwestiwn byddwn ni'n defnyddio Oes...?, e.e:

Mewn geiriau eraill Must I?/ Do I have to?
Does dim rhaid i fi There isn’t a necessity for me to
Mewn geiriau eraill I don’t have to
Rhaid i fi beidio There is a necessity for me to refrain from
Mewn geiriau eraill I must not
Amserau eraill
Roedd rhaid i fi There was a necessity for me to
Mewn geiriau eraill I had to
Bydd rhaid i fi There will be a necessity for me to
Mewn geiriau eraill I will have to
In full this would be - Mae’n rhaid i fi…, which literally means - There is a necessity for me to…
The - mae’n, - is not usually used in speech.
The question form of mae here is oes - is there? i.e:
