Oscar
UK[ˈɒskə]US[ˈɑːskər]
n
Any of a number of small statuettes awarded annually by the Academy of Motion Picture Arts and Sciences for achievement in the film industry.
n
A code word representing the letter O, used in radio communication.
Etymology
The name of the award is attributed to a 1931 anecdote in which Margaret Herrick, the Academy's librarian, remarked that the statuette resembled her uncle Oscar. The term was subsequently popularized by columnists and officially adopted by the Academy in 1939. While "Oscar" itself is a personal name of Old English origin, meaning "god spear," its application to the award is entirely arbitrary and based on this anecdotal resemblance, not on the semantic content of the original name. Thus, the word's journey into the lexicon of film is a classic example of a proprietary eponym becoming a generic term for the award itself.
Analysis
The word "Oscar" is a proper noun adopted as a common noun. It does not decompose into meaningful, reusable morphemes within the English language system.
