To Know Sumthin’
From Proto-Indo-European, Tenu Tendana inherits *ǵn̥h₃-sḱé- (“know”) in the form acnocerei. Like all regular verbs, acnocerei may be inflected in the usual ways, i.e. eio acnocu (“I know”), keia acnoceth (“She knows”), acnocensei esth (“[it] is [a] knowing”).
However, Tenu Tendana has a common slang expression in acnoc, which irregularly and illegally just chops the verb stem off and throws it away.
A speaker uses acnoc in several similar cases:
- Simply exclaiming Acnoc! is equivalent to “I get it!”
- Tagging acnoc? on the end of a statement is like adding on “you got it?”, “follow?”, “right?”, or “savvy?”

…that People Everywhere Will Use Language to Be Ironic Asshats.
I speculate that the word form originates in belittling sarcasm.
