In case and conjugation heavy languages like Finnish could the nominative/base verb or noun be presented. I don’t need all the iterations just the nominative.
like for “kasvoillaan”
both “on her face” and “kasvot” -”face” so I know the base
or like “emännälle” to the hostess
which base word is “hostess” - “emäntä”
That would make imput 20 times more effective because then I’m given the starting point and I can learn the grammar be seeing it 100,000 times and not having to look it up or guess every time.
