Etymology: "Moodless" is a plain compound: the noun "mood" with the suffix "-less," which means "without" or "lacking." Put together, it describes someone or something lacking a mood. The base noun "mood" has a surprising past. It was originally the same word as "mind" in Old English, from "mōd," meaning spirit, courage, or temper. Over time the sense narrowed toward a person's temporary emotional state, and grammatical "mood" (the indicative, subjunctive and so on) developed as a separate use. So "moodless" literally means lacking the mind-state or temper that the word once named outright. The adjective is built in the same way as many English words ending in "-less," such as "heartless" or "fearless," and it follows the pattern of describing a lack in a person's disposition or manner.
