Why is it not "an tíreolaíocht" - when Paul was studying chemistry and physics it was "an cheimic" and "an fhisic"?
Or even "an thíreolaíocht," for that matter.
It's not an thíreolaíocht because of DeNTaLS-DoTS.
Gah. Right, of course.
Tíreolaíocht is a feminine noun so it should be ní úsáidtear í. Additionally since the sentence is talking about the discipline of geography in general I think an tíreolaíocht with the definite article would be more appropriate.
Both of these are the questions I was going to ask.
This is not a copula construction because it's discussing a descriptive quality (important)? If it were "geography is not a school subject," e.g., would it be "ní (school subject) é tíreolaíocht?"
Yes, on both accounts.
Such an ignorant statement!
Should it not be "ní úsáidtear í" – on account of "tíreolaíocht" being a feminine noun?
