A term used in grammatical analysis to refer to the sequential arrangement of words in larger linguistics units. Some languages (e.g. English) rely on word-order as a means of expressing grammatical relationships within constructions; in others (e.g. Latin) word-order is more flexible, as grammatical relations are signalled by inflections. In later generative linguistics, languages with fairly fixed word-order are called configurational languages; those with fairly free word-order are non-configurational languages.
