Etymology
1. * Per Derksen, from Proto-Balto-Slavic *pertei, from Proto-Indo-European *per-. Baltic cognates include Lithuanian per̃ti (“to beat with a broom (in a bath)”), and wider Indo-European cognates include Sanskrit पृत् (pṛt), पृतन (pṛ́tana), पृतना (pṛ́tanā, “struggle, dispute, battle”), Old Armenian հարկանեմ (harkanem, “to beat”).
2. * Per Vasmer, cognates also include Latvian pḕrt (“to beat, to pound”), pirêtiês (“to quarrel”), Avestan 𐬞𐬆𐬱𐬀𐬥𐬀 (pəšana, “battle”), 𐬞𐬆𐬭𐬆𐬙𐬀𐬥𐬙𐬉 (pər^ətantē, “they are fighting”), Sanskrit परि (parí), परिन् (parin, “enemy”), Avestan 𐬞𐬀𐬭- (par-, “stand in the way”). Vasmer also includes various cognates beginning with *sp- that may reflect a separate Indo-European root *sperH- or *perH: Lithuanian spi̇̀rti (“to prop up”), 1sg. Lithuanian spiriù and Lithuanian ãtsparas (“support, stand”), and wider Indo-European cognates Latin spernō (“to spurn”), English spurn, Sanskrit स्फुरति (sphuráti, “to kick away, to shudder”), Avestan 𐬯𐬞𐬀𐬭𐬀𐬌𐬙𐬌 (sparaⁱti, “to trample, to push”).
3. Vasmer treats the Russian meanings "to move, to travel" as belonging to an entirely separate homophonous verb, also found in Old Church Slavonic перѫтъ (perǫtŭ, “they fly”), but this form more correctly stems from the Proto-Slavic verb *pьrati (“to fly”), and the Russian meanings are colloquial and likely to be extensions of the underlying meaning "to drag".
4. * Rix considers the root to derive from *sperH- (“to kick”). See: Classical Armenian '
հարկանեմ', Latin '
spernō', English '
spurn', Sanskrit '
स्फुरति'.
