Ainesanat
Ainesanat are, easily explained, words that cannot be counted or arent usually counted. My Finnish teacher called them substance words, because they describe a substance rather than the single parts of which said substance is made up of
examples would be hiekka (sand), ruoka (food), maito (milk), and also things like omena (apple).
the difference between, for example, paljon omenaa and paljon omenoita is that in the first sentence, you treat apple as a substance (eg. there is a lot of apple in the cake), and in the second you treat apples as countable pieces (eg. i have to buy a lot of apples)
ainesanat always are a partitive singular object
some words are only ever ainesanat, whereas others can be both ainesanat and totaaliobjektit. generally, if you wouldnβt count the thing you are referring to you use partitive singular, as the word is an ainesana then
