analog
Pronunciation
Etymology
It is the American spelling of analogue,[2][3][4] borrowed from French analogue (“analogous; an analogous thing”),[5][6][7][8] from Ancient Greek ἀνάλογον (análogon), the neuter of ἀνάλογος (análogos, “proportionate”),[6][7][9] formed from ἀνά (aná, “according to”) and λόγος (lógos, “ratio, proportion”).[2][9][1] The American Heritage Dictionary and Etymonline put analogus between the Greek and French words.[5][2] The OED takes the English word partly from French and partly from the Greek, and notes the earlier analogon.[7] analogous and analogy are from the same Greek adjective.[9][5]
Earliest recorded meaning
In zoology and botany, a living species that corresponds to a fossil one: 1808.[7] Merriam-Webster dates the noun to 1804,[10] and Barnhart and Etymonline to 1826, "an analogous thing";[6][2] the Greek form analogon was used in English in 1810.[2]
Semantic evolution
The 19th-century senses were scientific: an organ like another in function but not in origin (1817), a chemical compound closely like another in structure (1837), and in general a thing parallel to another (1837).[7][2] The modern technical sense comes from computing: an analogue computer, recorded from 1941, works with quantities such as voltage that vary continuously and stand in for the numbers, by analogy with them;[7][2] it is the opposite of digital.[7][2] From there the adjective spread to signals (1948), devices (1969) and sound recordings (1979),[7] and since 1986 the noun has also meant analogue technology or media in general.[7] Merriam-Webster now also gives the adjective the broad sense "not computerized".[10] A synthetic food made to imitate a natural one has been called an analogue since 1966.[7]

Usage notes
Collins treats analog as the US spelling of analogue in all its senses, and as the spelling generally preferred in the computer industry;[3] the Shorter Oxford likewise gives analog as American and, generally, computing usage.[4]
