1 einga-vinr
m. an only friend, bosom friend, Nj. 77. In mod. usage einka- (q. v.) is used instead of einga-, which is an obsolete form; and even in old MSS. both forms occur, e. g. Stj. (l. c.), v. l.: Þiðr. 130 spells ‘einka-,’ and it even occurs in old vellums as 623, p. 41; einka-sonr, Luke vii. 12.
