-ntaa

From Proto-Finnic *-ntadak, possibly even from Proto-Uralic *-mta-, but in any case equal to -(e)n(e)- +‎ -taa (the causative form of -eta, with which the stem-final vowel change is shared).

-ntaa (front vowel harmony variant -ntää, stem -nta-, linguistic notation -ntA- or -ntAA)

1. Forms factitive verbs from adjectives and names of languages, meaning "causing to become" or "making"., or in the case of languages, to translate into that language; -en, -fy.

   ‎pieni (“small”) + ‎-ntaa → ‎pienentää (“to shrink”)

   ‎paksu (“thick”) + ‎-ntaa → ‎paksuntaa (“to thicken”)

   ‎suuri (“large”) + ‎-ntaa → ‎suurentaa (“to magnify”)

   ‎englanti (“English”) + ‎-ntaa → ‎englannintaa (“to translate into English”)

The suffix is added to the genitive singular (weak grade) stem. A preceding stem-final -a-, -ä- changes to -e- (see -eta for more on this change), except in some newer derivations, such as kuvantaa and kustantaa.
