[Middle English scanden, scannen, to scan a verse, from Latin scandere, to climb, scan a verse.]

scanʹnable adjective

scanʹner noun

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. But a thorough search can change into a quick one, as it seems to have done in the case of the verb scan.
