[Swager]
** English
*** Etymology 1
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 [ang] and [ang] in some East Midlands dialects, which are derived from attested Old English and Middle English words sweger (see http://bosworth.ff.cuni.cz/029630) and sweor (see http://bosworth.ff.cuni.cz/029676) , respectively. Ultimately derived from [en], from [en].
