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.
