Vocab: vastutama - to be responsible
to be responsible; to be responsible for making sure something works properly or follows the rules; to be accountable for the results of one’s actions
Building blocks
vastu- → against/in response to
-ta- → causative suffix (to make something happen)
-ma → infinitive ending
So vastutama literally means to answer in response.
Originally connected to “vastu vastama” (to answer back), which explains why vastutama also includes the idea of being accountable for consequences, not just “being in charge”.
