Etymology
ADHD is an initialism, a modern lexical formation coined in the late 20th century within the field of clinical psychology and psychiatry. It is an abbreviation for the diagnostic label "Attention Deficit Hyperactivity Disorder." Each component word of the full term has its own distinct etymology: "attention" from Latin attendere (to stretch toward), "deficit" from Latin deficere (to fail, be lacking), "hyperactivity" from Greek hyper- (over) plus Latin activus (active), and "disorder" from Old French desordre. The initialism itself follows the common English practice of creating pronounceable acronyms from technical terminology for efficiency in both professional and lay discourse.
Analysis
This is an initialism, not a compound word formed from classical morphemes. It stands for Attention Deficit Hyperactivity Disorder.
