[Middle English scanden, scannen, to scan a verse, from Latin scandere, to climb, scan a verse; see skand- in Indo-European roots.]
scan'na·ble adj.
Word History: In the 1969 edition of The American Heritage Dictionary a dead issue was buried by our Usage Panel, 85 percent of whom thought it was acceptable to use scan in the sense "to look over quickly," though the note stated that this was less formal usage. The usage issue was raised because scan in an earlier sense meant "to examine closely." From a historical perspective it is easy to see how these two opposite senses of scan developed. The source of our word, Latin scandere, which meant "to climb," came to mean "to scan a verse of poetry," because one could beat the rhythm by lifting and putting down one's foot. The Middle English verb scannen, derived from scandere, came into Middle English in this sense (first recorded in a text composed before 1398). In the 16th century this highly specialized sense having to do with the close analysis of verse developed other senses, such as "to criticize, examine minutely, interpret, perceive." From these senses having to do with examination and perception, it was an easy step to the sense "to look at searchingly" (first recorded in 1798), perhaps harking back still to the careful detailed work involved in analyzing prosody. The sense of looking something over to find a specific set of things was eventually broadened to include looking over the surface of something, with or without close scrutiny of the details. From this was born the modern usage of scan as a verb meaning "look over quickly."
1398, "mark off verse in metric feet," from L.L. scandere "to scan verse," originally, in classical L., "to climb" (the connecting notion is of the rising and falling rhythm of poetry), from PIE *skand- "to spring, leap" (cf. Skt. skandati "hastens, leaps, jumps;" Gk. skandalon "stumbling block;" M.Ir. sescaind "he sprang, jumped," sceinm "a bound, jump"). Missing -d in Eng. is probably from confusion with suffix -ed (see lawn (1)). Sense of "look at closely, examine" first recorded 1550. The (opposite) sense of "look over quickly, skim" is first attested 1926. The noun is recorded from 1706. Scanner as a type of mechanical device is recorded from 1927.
to examine carefully Example: He scanned the horizon for any sign of a ship.

SCAN 1. ["A Parallel Implementation of the SCAN Language", N.G. Bourbakis, Comp Langs 14(4):239-254 (1989)]. 2. A real-time language from DEC. [Are these the same language?] (1994-11-01)
scan 1. (computer peripheral) See scanner. 2. (circuit design) See scan design. 3. (functional programming) See scanl, scanr. 4. An algorithm for scheduling multiple accesses to a disk. A number of requests are ordered according to the data's position on the storage device. This reduces the disk arm movement to one "scan" or sweep across the whole disk in the worst case. The serivce time can be estimated from the disk's track-to-track seek time, maximum seek time (one scan), and maximum rotational latency. Scan-EDF is a variation on this. (1995-11-15)
