swager

/ˈswäɡ(.)əɹ/ · Midlands /ˈswɛ(ː)ɡ(.)ə(ɹ)/

Etymology Recorded in neither Old English nor Middle English. Perhaps a borrowing from Dutch or Low German, but this derivation is rather unlikely due to the presence of the words like sweġer (“mother-in-law”) and swēor (“father-in-law”) in some East Midlands dialects, which are derived from attested Old English and Middle English words sweger and sweor, respectively. Ultimately derived from Proto-Germanic *swēgraz (“husband's brother”), from Proto-Indo-European *swéḱuros (“husband's father”).
