A translation apparatus that can perform translation based on a correct syntax, a syntax evaluation apparatus employed in the translation apparatus, a syntax evaluation method, and a syntax evaluation program are provided. A syntax evaluation unitincludes a grammatical element guessing partthat guesses a grammatical element that should be connected before and after or after a word string indicated by first fragment data, and a grammatical element complementing partthat complements, based on the guessing result of the grammatical element guessing part, the first fragment data as necessary to generate second fragment data. When the grammatical element guessing partguesses a grammatical element, the grammatical element complementing partcomplements, at a location to which the grammatical element of the word string indicated by the first fragment data should be connected, a tag indicating the grammatical element in order to generate the second fragment data. When the grammatical element guessing partdoes not guess a grammatical element, the grammatical element complementing parthandles the first fragment data as the second fragment data.
