lexical analysis

   Also found in: Acronyms, Wikipedia 0.03 sec.
(programming)lexical analysis - (Or "linear analysis", "scanning") The first stage of processing a language. The stream of characters making up the source program or other input is read one at a time and grouped into lexemes (or "tokens") - word-like pieces such as keywords, identifiers, literals and punctutation. The lexemes are then passed to the parser.
