This paper describes a computerized system (PANVS) for the syntactic analysis of Arabic sentences. The system parses both nominal and verbal sentences. It is composed of several components including a lexical analyzer, a morphological analyzer, an automatic spelling error corrector and a parser. The parser is based on Definite Clause Grammar formalism. PANVS has been written in TURBO PROLOG using an IBM PS/2 model 60 microcomputer.
