A translation machine having a storing unit for storing information of words and grammar rules, the translation machine being capable of translating sentences described in a source language into a target language includes a unit for dividing an input sentence in the source language into its morphological elements and for generating a mark-inserted sentence by adding S18 a mark which represents the degree of ambiguity of the detected morphologic elements a unit connected to the dividing unit for analyzing a syntax of the morphologic elements in accordance with the information stored in the storing unit and a unit connected to the analyzing unit for converting a structure of the syntax obtained in the dividing unit into a structure of syntax in the target language so that translated sentence is generated on a basis of the syntax structure in the target language obtained by the converting unit. Interpretative ambiguity or indeterminacy exists where a word for translation has two or more parts of speech determined for it by the morphological analysis. <IMAGE>
