Definition swear

Etymology 1

From Middle English sweren, swerien, from Old English swerian (“to swear, take an oath of office”), from Proto-Germanic *swarjan? (“to speak, swear”), from Proto-Indo-European *swer- (“to speak, talk”). Cognate with West Frisian swarre (“to swear”), Saterland Frisian swera (“to swear”), Dutch zweren (“to swear, vow”), Low German swören (“to swear”), sweren, German schwören (“to swear”), Danish sværge, Swedish svära (“to swear”), Icelandic sverja (“to swear”). Also cognate to Albanian var (“to hang, consider, to depend from”) through Proto-Indo-European.

The original sense in all Germanic languages is “to take an oath”. The sense “to use bad language” developed in Middle English and is based on the Christian prohibition against swearing in general (cf. Matthew 5:33-37) and invoking God’s name in particular (i.e. frequent swearing was considered similar to the use of obscene words).
