Etymology Origin:
Coined in 1952 as an acronym for "Self-Contained Underwater Breathing Apparatus." Over time, "scuba" evolved into a standalone noun and verb, losing its acronymic awareness in everyday usage. The morphemes scu and ba reflect the original acronym's logic but are not standalone prefixes/roots in other contexts.
