@unmind i love all the inflections in sanskrit and all the cool compounds u can form. the grammatical feature thats my favorite is pretty silly but it’s the converb form in -tvā or -ya (depending on whether the verb has a prepositional prefix or not) like in śloka 2 line 2 of chapter 1 of the gita u get
आचार्यम् उपसंगम्य राजा वचनम् अब्रवीत्
where उपसंगम्य upsaṃgamya expresses “having approached,” in 1 inflected verb form. i just rlly like how it sounds meow. especially w/ the verb कृ kṛ (like in karma) where u get the form कृत्वा kṛtvā “having done/made/caused”
