Here's something that I've never encountered before in any language, nat- or con-. According to Aikhenvald's Languages of the Amazon, the language of Matses has words that differ depending on whether the main verb in the clause is transitive or intransitive. She offers as examples a pair of sentences: kumanpen-ek mibi ekkuk-te bun-e-bi intensely-INTR 2ABS kiss:TRANS-COMPL want:INTR-NONPAST-1SUBJ I strongly desire to kiss you. kumanpen-en mibi ekkuk-te bun-e-bi intensely-TRANS 2ABS kiss:TRANS-COMPL want:INTR-NONPAST-1SUBJ I want to kiss you forcefully. In Matses, this happens with manner adverbs, postpositions, locationals, and various suffixes and enclitics referring to manner and direction. Mind blown. I would never ever have thought of something like this on my own. Have you encountered this? Put this in a conlang? Found something else that blew your mind? -S -- Sylvia Sotomayor The sooner I fall behind the more time I have to catch up.
