1948, abbreviation of long-playing phonograph record.
The most revolutionary development to hit the recording industry since the invention of the automatic changer is the Long Playing record, which can hold an entire 45-minute symphony or musical-comedy score on a single 12-inch disk. ... The disks, released a few weeks ago by Columbia Records and made of Vinylite, have phenomenally narrow grooves (.003 of an inch). They are played at less than half the speed of the standard old-style records. ["Life" magazine, July 26, 1948]
[LP etymology, LP origin, 英语词源]
phenomenal (adj.)youdaoicibaDictYouDict
1803, "of the nature of a phenomenon," a hybrid from phenomenon + -al (1). Meaning "remarkable, exceptional" is from 1850.
[Phenomenal] is a metaphysical term with a use of its own. To divert it from this proper use to a job for which it is not needed, by making it do duty for remarkable, extraordinary, or prodigious, is a sin against the English language. [Fowler]
