"Yma" may also mean "this" so could it also mean "I am making this breakfast"?
You'd need the definite article - Dw i'n gwneud y brecwast yma - although that's also slightly ambiguous, i.e. it could mean "I'm making this [particular] breakfast" or "I'm making the breakfast here [not you]". If you needed to, you could avoid the ambiguity by using "hwn", "Dw i'n gwneud y brecwast hwn".
To my recollection, it can; for example, "Beth wyt ti'n gwneud?" means "What are you doing?"
If I remember my gcse correctly gwneud means to do or to make, so yes - useful verb to know.
I can't help but picture this being said by an angry New Yorker frying bacon in the middle of the street. "Hey, watch it, I'm makin' breakfast here!"
To say this it would have to be "ma" not "my" Yma - here ma - this
Yna - there na - that
Not really. "'ma" is just a contraction of "yma", "'na" of "yna".
yma / yna = here / there
y ... yma / yna = the ... here / there = this / that ...
e.g. y bara yma = this bread; y dyn yna = that man
You can contract "yma/yna" in informal language, especially after a vowel e.g. y bara 'ma, y dyn 'na.
I think he was replying to DamonLordAuthor's comment, though he didn't use the reply functionality.
How is "gwneud" pronounced? It sounds like the audio is saying "made".
I sounds like "gneud" i.e. rhymes with English "made" but with "gn" at the front. The "w" means your lips are rounded when you pronounce the "gn" bit. So round your lips and then open them as you say "gneud". Sorry that's the best I can do in text!
The "w" is hardly heard, and the "g" is usually dropped too (at least round here, Ceredigion/north Pembs), so it ends up sounding more or less like "nade".
Not quite. /j/ is the sound of [y] in yellow or [j] in German ja or [i] in Welsh Ionawr.
You're right, it can be analysed as [i], but it also can be analysed as [j]. John Wells the phonetician, and Welsh speaker, mentions this in his work. I personally think it's a better way to represent the behaviour of Welsh diphthongs, especially when it comes to representation of things like complementary quantity, e.g. llai, llaid S: [ɬajˑ, ɬajˑd], N: [ɬajˑ, ɬajdˑ]; lleia, lleidiog S:[ɬejˑa, ɬejˑdjɔg], N:[ɬejˑa, ɬejdˑjɔg]. Transcription such as [ɬaiˑ, ɬaiˑd, ɬeiˑdjɔg] etc. wouldn't really work.
So how would you write the second part of a falling diphthong such as Welsh ‹eu›? As far as I know, it is not pronounced as two separate vowels as in /ei/.
