• The target language words are correct, but in the wrong linear order according to the syntactic rules of the target language.
• An error of incorrect word structure has occurred if an otherwise correct target language word (or term) is expressed in an incorrect morphological form, e.g., case, gender, number, tense, prefix

• Violates the spelling as stated in a client glossary,
• Violates the accepted norms for spelling in the target language,
• Is written in an incorrect or inappropriate writing system for the target language.
