Computer-aided translation program. In essence a database that stores translated sentences (translation units or segments) with their respective source segments in a database (the “memory”). For each new segment to be translated, the program scans the database for a previous source segment that matches the new segment exactly or approximately (fuzzy match) and, if found, suggest the corresponding target segment as a possible translation. The translator can then accept, modify or reject the suggested translation.

Not to be confused with machine translation!
