Etymology
The word 'disinfect' is a layered construction built upon the Latin verb facere, meaning "to do" or "to make." The past participial stem fect- combines with the prefix in- (not) to form infect, which originally meant "to dip in, stain, or taint." The addition of the reversing prefix dis- (undo, remove) logically creates the sense of "undoing the state of being tainted or infected." Thus, the literal morphemic journey from "make not" to "taint" and finally to "remove taint" elegantly captures the modern abstract meaning of cleansing by destroying disease-causing agents.
