Etymology: "Mannerless" is a plain compound: "manner" with the suffix "-less," meaning "without." Its earliest form appears in Middle English as "manerles," so it is a word that has been in the language for centuries, built from parts English speakers already had on hand. The root "manner" traces back through Anglo-French and Old French to Latin "manuarius," meaning "of the hand," from "manus," hand. The sense that gave us "manner" moved from the physical handling of something to the way a person conducts themselves, so a manner was originally a kind of practiced handling before it became a matter of social bearing. Adding "-less" to that idea gives a word for lacking that bearing altogether. Because the suffix is so productive, the word is easy to parse, and it sits comfortably beside similar formations like "graceless" and "tactless." Its meaning has stayed close to its construction: it describes someone who simply lacks the courtesy the word's parts imply.
