Proto-Germanic *swestēr Proto-West Germanic *swester Old English sweostor Middle English suster English sister Inherited from Middle English suster, from Old English sweostor, from Proto-West Germanic *swester, from Proto-Germanic *swestēr, from Proto-Indo-European *swésōr. Doublet of soror.

In standard English, the form with i is due to contamination with Old Norse systir (“sister”). The plural sistren is from Middle English sistren, a variant plural of sister, suster (“sister”); compare brethren. The sense for "Adelpha-genus butterfly" is a semantic loan from translingual Adelpha, itself from Ancient Greek ἀδελφή (adelphḗ, “sister”).
