ahtumat

noun. supper, supper, *(lit.) maker’s meal

A word for “supper” in the Declension of Nouns (DN) from the early 1930s, a combination of ᴹQ. ahto “maker” and ᴹQ. mat “meal” (PE21/33, 37) hence more literally “maker’s meal”, likely a reference to a meal taken after working. Given that the stem of mat “meal” is matt-, this word might be expected to have the stem form ahtumatt-, but its inflections show both single t and double tt, indicating that the historical stem might have become archaic and reduced to ahtumat- instead. Since the reduced stem is trisyllabic and ends in two light syllables, it often triggers prosodic lengthening as in genitive ahtumáto with lengthening as opposed to (archaic?) ahtumatto from the original stem ahtumatt-.
