Etymology: "Rescan" is a plain formation: the prefix "re-", meaning "again", attached to "scan". The prefix comes from Latin "re-", which carried the same sense of repetition or backward motion, and it reached English through Old French and Middle English. The word "scan" has a longer and more winding past. It traces back through Latin "scandere", meaning "to climb" or "to step", a sense that survives in the idea of scanning a line of verse by counting its metrical feet, which is where English first used it. From that verse-measuring sense, "scan" came to mean examining something closely, point by point, and eventually scanning an image or document for storage or review. Adding "re-" to it gives a plainly literal meaning: to go over the same ground again, this time to catch what the first pass missed.

Synonyms: re-examine, recheck, review, reassess, reinspect
