Analytic language

An analytic language is a language that conveys grammatical relationships without using inflectional morphemes. A grammatical construction can similarly be called analytic if it uses unbound morphemes, which are separate words, and/or word order. Analytic languages are in contrast to synthetic languages.

A related concept is the isolating language, which is about a low number of any type of morphemes per word, taking into account derivational morphemes as well. A purely isolating language would be analytic by necessity, lacking inflectional morphemes by definition. However, the reverse is not necessarily true: a language can have derivational morphemes while lacking inflectional morphemes. For example, Mandarin Chinese has many compound words, giving it a moderately high ratio of morphemes per word, yet, since it has almost no inflectional affixes at all to convey grammatical relationships, it is a very analytic language.

The term "analytic" is commonly used in a relative rather than an absolute sense. English has lost much of the inflectional morphology of Proto-Indo-European, Proto-Germanic and Old English over the centuries and has not gained any new inflectional morphemes in the meantime, making it more analytic than most Indo-European languages. For example, while Proto-Indo-European had inflections for eight cases in its nouns, standard English has lost all of them.
