We've looked at verb forms that follow questions Ble, Pryd, Faint, Sut and Pam.
Let's look at two question forms that are not quite as straightforward Pwy and Beth
Pwy sy?/Pwy ydy? Beth sy?/Beth ydy? As you know in the present tense pwy can be followed by either sy or ydy or yw
Agnes says: Pwy yw e - and Pwy sy wrth y drws nawr eto - Who's at the door now again Note the following questions
Pwy ydy hi? - Who's she? Pwy ydy'r bachgen? - Who's the boy? Pwy ydy'r perchennog? - Who's the owner?
Beth ydy e? - What is it? Beth ydy'r swn yna? - What's that noise? Beth ydy hwn? - What's this?
You'll notice that the forms that follow ydy are either nouns or pronouns.
Answers to these questions in day to day conversation are usually one word.
Pwy ydy e? - Rhodri Beth ydy hwn? - Cwch
If however the answer needs to be emphasised the object replaces the pwy.
Pwy ydy hi? Beca ydy hi siwr iawn - She's Beca of course
Other persons follow the usual patterns
Pwy wyt ti? Beth ydyn nhw? When and Pwy and Beth are not followed by nouns or pronouns to convey who is or what is then sy is the form that is used.
Pwy sy'n canu? - Who's singing? Pwy sy'n galw? - Who's calling? Beth sy'n bod? - What's the matter? Beth sy'n las? - What's blue? Beth sy ar y llawr? - What's on the floor? Beth sy ar y teledu? - What's on television? Pwy sy yn y ty bach? - Who's in the toilet?
Pwy sy yna? - Who's there?
Answers to these questions in everyday conversation are usually one word unless one needs to emphasise something.
Pwy sy yna? - Fi or Fi sy yma
Welsh has two words for to start. Agnes says: Mae'n bryd i chi gychwyn am yr ysgol. - It's time you started for school.
And Brian says: Mae Jenny Saunders yn dechrau colli arni ei hun - Jenny Saunders is starting to go off her head
Cychwyn/Dechrau
Cychwyn is the form used when setting off somewhere.
Dechrau is used in other contexts for example:
