white arm
English
Etymology
Calques exist across Romance languages and English (for example, arme blanche and arma blanca). The uncommonness of the term in English might suggest that the English term was calqued from the French but was not widely adopted.
Noun
white arm (plural white arms)
- (uncommon) Synonym of cold weapon.
Usage notes
In English, familiarity with this term is likelier to occur with military experts than with laypersons. The terms edged weapon, bladed weapon, and cold weapon are the ones usually used in English.
