Note: While "laser" is technically an acronym (Light Amplification by Stimulated Emission of Radiation), it is now treated as a standalone word in modern usage. For memorability, we present it as a single morpheme here, as it no longer retains its acronymic structure in everyday language.
Etymology Origin:
Coined in 1960, "laser" originated as an acronym describing its scientific mechanism. Over time, it evolved into a lexicalized noun, shedding its acronymic ties. The word reflects mid-20th-century advancements in quantum physics, where precision terminology was condensed into memorable forms. Unlike older compound words, "laser" demonstrates how modern English adapts technical abbreviations into common vocabulary.
