Abstract: A translation machine is arranged to derive two or more syntaxes from one original sentence, determine which of the syntaxes is the most approximate according to a syntax priority rule given by a user or a manufacturer and output a translated sentence based on the most approximate syntax. The translation machine includes a memory, a translating module and a main CPU as main components. The memory serves to store a partial structure of each syntax and a syntax priority rule containing a numerical value indicating a priority of the partial structure and an incidental condition of the syntax. The translating module serves to collide the syntax priority rule stored in the memory with the syntax of the original sentence and giving a proper evaluating value to the syntax of the original sentence. The main CPU serves to output the translated sentences on the syntaxes derived from the original sentence according to their larger evaluating values.
