Reconstruction:Proto-Balto-Slavic/stāˀwēˀtei

Etymology
Ultimately from, likely verbalized from the perfect w-participle (Van Wijk, Stang). Kortlandt in particular reconstructs pre-Balto-Slavic.

Outside of Balto-Slavic, has been compared with 🇨🇬, 🇨🇬 (both with causative sense), but common origin is unlikely for phonetic and semantic reasons. The medial -w- in Germanic is considered (per Rasmussen) as epenthetic to fill the hiatus within *-ōe- > *-ōwe-.

Reconstruction notes
Modern descendants point towards columnar acute root-stress (except for the infinitive in Lithuanian with ictus on the thematic vowel). Kortlandt however reconstructs circumflex for the overall derivational pattern, attributing the acute in stāˀwēˀtei due to relevelling with related imperfect forms.

Verb

 * 1) to stand (stative)

Conjugation
Fixed accent.

Possibly originally with perfect endings (per Kortlandt): (3p. sg.) ~  (3p. pl.)

Modern descendants have reanalyzed the conjugation as i-present with ē-preterite. Athematic present is attested in Old Lithuanian.
