The act of removing a sword or weapon from its sheath; drawing or unsheathing.
From dis- + sheathing (from sheath, Old English scæð). The dis- prefix here means 'to remove from' rather than 'to negate,' a common usage pattern in verbs related to physical separation.
Military terminology preserved this word long after it became archaic in everyday English—the romantic image of a knight disheathing his sword inspired countless adventure stories and still appears in historical fiction today.
