Helo! Rhaid i mi ofyn cwestiwn unwaith eto. Mewn llawer o ieithoedd eraill mae amryw fathau o ddweud bod rhaid i ti 'neud rhywbeth (e.e. yn Saesneg 'I have to do s.th.', 'I am to do s.th.', 'I'm told to do s.th.', etc.). Pa fathau oes yn Gymraeg o ddweud hynny, ar waha+n o'r gystrawen uchod. [In English (as in many other languages) there are several possibilities to say that you have to do something: e.g. in English there's this 'I am to help you', 'I'm told to do something', etc. What possibilities does Welsh have apart from the _rhaid_-construction to express such notions?] Pob hwyl a diolch am eich ateb!
