Etymology: ADHD is an acronym for "attention-deficit/hyperactivity disorder," so its letters spell out a clinical label rather than an older everyday word. Before that name settled, clinicians described the same pattern of distractibility and restlessness under other labels, and the diagnostic name changed as the manuals were revised. Each component has its own history. "Attention" comes from Latin "attendere," "to stretch toward." "Deficit" comes from Latin "deficere," "to fail or be lacking," and it entered English through French. "Hyperactivity" combines Greek "hyper," "over," with "activity," from Latin "activus," "active." Put together, the name describes a shortfall in directing attention alongside excess motion.
