Dim ond dwy eithriad sydd, lle bydd atebion Cymraeg yn wahanol i atebion llawn Saesneg:
There are two exceptions to Welsh answers being like full English answers:

1)         Yr Amser Gorffennol - Yes/No   / Past Tense yes and no, e.g:
Est ti ma’s?             Welon nhw’r gêm?  Do/Naddo
Did you go out?     Did they see the game?

2)         Cwestiynau Pwysleisiol / Emphatic yes and no, e.g:
Ma’s est ti?               Nhw yw’r gorau?             Nyrs yw e?  Ie/Nage
Out you went?         They were the best?       A nurse he is?

Dyw cwestiynau pwysleisiol ddim yn dechrau gyda berf. Yn syml, byddwch chi'n gwneud cwestiwn pwysleisiol mewn unrhyw amser, drwy symud rhan y cwestiwn byddwch chi eisiau ei physleisio i ddechrau'r frawddeg. Pan fydd hyn yn digwydd, Ie/Nage fydd yr atebion, ni waeth beth fydd yr amser, e.e:
Emphatic questions
are those which do not start with a verb. An emphatic question can be formed in any tense by putting what you are emphasising first. When this happens the answers are always Ie/Nage regardless of the tense, e.g:

Y Presennol / Present

Wyt ti’n nyrs?    Are you a nurse?
Ydw/Nac ydw

Y Presennol - Gyda phwyslais / Emphatic

Nyrs wyt ti?         A nurse you are?  (noun first - nurse)
Ie/Nage

Y Gorffennol / Past

Aeth Ffred?        Did Ffred go?
Do/Naddo

Y Gorffennol - Gyda physlais / Emphatic

Ffred aeth?        Ffred  went? (noun first - Ffred)
Ie/Nage
