Reconstruction notes
The Baltic and Slavic forms do not exactly agree, as the Slavic form is missing the short i that is present in the Baltic forms.

Derksen explains, citing Kortlandt:
 * Baltic from the (zero grade) nasal-infixed present.
 * Slavic from the aorist stem.

Dialectal 🇨🇬, (for standard, ), 🇨🇬 according to Kortlandt show the PIE ablaut alternation between the singular -neh₂- [sic -neh₃-?] and the plural -nh₂- in the nasal present (see the paradigm at ).

Karulis proposes a simplistic (and likely outdated) theory that dialectal 🇨🇬, 🇨🇬 (prefixed forms still in common use:, ) should be treated as primary and the "thematic" zināt/žinoti as their iterative derivations, either way both from PIE zero grade.
