My first (rejected) guess was "is the wind blowing" - guess this would be "an bhfuil an ghaoth ag séideadh"
If the wind didn't blow, it wouldn't be a wind
Bodily wind (which is another meaning of gaoth) doesn’t necessarily blow.
Wait...that’s really a term for “fart”?
"gaoth" can mean "flatulence" as well, yes
That's not quite the question that Codester3 asked, though, it is?
The Irish for "fart" is broim (both a noun and a verb).
Is this a way of saying "Is it windy?"
An bhfuil sé gaofar? - "Is it windy?"
Ask not for whom the wind blows, it may blow for you.
