Pronunciation

scope1 extent, range

Borrowing
First attested

Borrowed from
Italian scopo
Ultimate origin
Ancient Greek (σκοπός)

Etymology

The extent is borrowed from Italian scopo (“aim, purpose, target”),[1][4][5][2] from Latin scopus, from Ancient Greek σκοπός (skopós, “aim, target; watcher”), related to σκοπέω (skopéō, “to look at, consider”),[1][4][5] which Watkins derives from PIE Proto-Indo-European *spek- (“to observe”) (see spy).[4][1]

Earliest recorded meaning

Room to act, free play: 1534 in Barnhart, the 1530s in Etymonline;[1][4] SOED's first sense is a target, a mark for shooting at (mid-16th century).[6]

Semantic evolution

Something aimed at, an ultimate aim, is from the 1550s, and the classical sense of a target from the 1560s, now obsolete.[4][7] Extent in space is by the 1590s.[4] The range the mind can reach is first recorded in Shakespeare's Sonnets, about 1600.[1][4] The sphere in which an activity operates is by 1830.[4] At sea, the scope is the length of cable at which a ship rides at anchor (17th century).[5][8] The verb, to calculate the scope of, is from 1807, and the slang scope out, to look over, by 1985.[4]
