swestēr ˈswes.tɛːr ᛊᚹᛖᛊᛏᛖᚱ
noun feminine r-stem sister Remodeled based on analogy with *-tēr kinship words, from Proto-Indo-European *swésōr. This may well have been triggered by the insertion of *-t- in the cluster *-sr- that arose in several oblique case forms, a change which is also found in *þimstr (‘dark, dusky’) and *Austrǭ (‘springtime, Easter; a goddess of spring and fertility’) and is therefore likely a regular sound change in Proto-Germanic.
