Thank you. That helps. Do you you know, though, how to tell which words to use to use as adjectives and which to use as adverbs? It doesn’t seem quite parallel to English, and apps/websites like Foiclóir and Teanglann don’t seem to indicate the difference.
Only a few adjectives, containing a subjective value judgement, often referring to weather or personal condition
It depends on dialect, so the list isn’t exhaustive:
maith, olc, dona, aoibhinn, álainn, deas, breá, iontach (so acc. to Ó Siadhail in “Learning Irish”). I’d add measartha, ainnis, too.
