The distributive-temporal of a noun is a grammatical case specifying when and how often something is done.
This case (-nta/-nte) in Hungarian can express how often something happens (e.g. havonta "monthly", naponta "daily", telente "every winter", reggelente "every morning"); it can alternate with the distributive case in words of temporal meaning.
This adverb type in Finnish can express that something happens at a frequent point in time (e.g. "on Sundays" is sunnuntaisin), or an origin (e.g. "born in" is syntyisin).
It is restricted to a small number of adverb stems and nouns, mostly those with the plural formed with an -i- suffix.
