Is "inniu" pronounced like "In-yuh"? Sorry if I'm way off the mark!
As a Welsh speaker it looks very close to "heno" which also means "today", and is handy for me in remembering this. :)
I've just noticed that holding down 'shift' + 'ctrl' repeats audio. You can stop and repeat anywhere in the clip by hitting 'space' whilst holding down these keys. Very useful. I wish I could find a way of slowing it down, but I doubt that'd be possible in a satisfactory way with real voice recordings.
This is probably something everyone else discovered eons ago, but it's just made me happy.
In Microsoft Edge and Firefox I just have to hit the spacebar to repeat the audio.
You can slow the audio down by accessing it directly at this URL:
Right click on the player to change the Play Speed. (Microsoft Edge does a much better job of slowing it down).
"today" can be either a noun or an adverb. It an adverb in "Is your birthday today?", and therefore the grammatically equivalent phrase in Irish is An bhfuil do bhreithlá inniu?.
"today" is a noun in “Is today your birthday?”. As you are comparing two nouns, you use the copula - An é inniú do bhreithlá?
"Is it your birthday today?", "Is today your birthday?", "Is your birthday today?" all overlap in meaning, but grammatically, they are quite different.
Anther alternative that is accepted as correct, though, is "Is it your birthday today?", which seems (to me) to be the most natural way to ask this question in English. Hmm, is there some alternative construction in Irish (maybe using the pronoun é) that would match this way of expressing the idea?
