Hello everyone I am new to Irish (I literally started studying an hour ago) and I wonder if you could help me at all.
I came across a table in Mícheál ó Siadhail's ''Learning Irish'' which explains the use of the autonomous forms ''Táthar'' and ''Níltear''.These I grasp so far but it then mentions the construction:
An (or Nach) bhfuiltear sásta anseo.
Do they mean:
''Are people/is one satisfied here?''
and
''Are people not satisfied here?''?
This might seem really obvious to you all but I'd rather sort this out from the off.
Thanks in advance.

tá -bhfuil

Bhfuil is the defendant form that comes after a verbal particle (so are the An and Nach, at least historically).

In the past, bhí -rabh is another example.

The translation I take it comes from the book?

No the ''translations'' are mine(not the English I would use but closer to the non idiomatic Translations given in the book), anyway after looking up verbal particles in the book there happened to be a an exact translation of ''Nach bhfuiltear sásta anseo?'' which matched my above attempt.
P.s Sásta is translated in the book as ''content'' but I mistakenly wrote ''satisfied''
Thanks anyway.

No there is nothing wrong with your gloss, but other people could tell you that; less would have said anything about the dependent form
