Morphological typology

Morphological typology is a way of classifying the languages of the world that groups languages according to their common morphological structures. First developed by brothers Friedrich von Schlegel and August von Schlegel, the field organizes languages on the basis of how those languages form words by combining morphemes. Two primary categories exist to distinguish all languages: analytic languages and synthetic languages, where each term refers to the opposite end of a continuous scale including all the world's languages.

Analytic languages

Analytic (or "isolating") languages show a low ratio of morphemes to words; in fact, the correspondence is nearly one-to-one. Sentences in analytic languages are composed of independent root morphemes. Grammatical relations between words are expressed by separate words where they might otherwise be expressed by affixes, which are present to a minimal degree in such languages. There is little to no morphological change in words: they tend to be uninflected. Grammatical categories are indicated by word order (for example, inversion of verb and subject for interrogative sentences) or by bringing in additional words (for example, a word for "some" or "many" instead of a plural inflection like English -s). Individual words carry a general meaning (root concept); nuances are expressed by other words. Finally, in analytic languages context and syntax are more important than morphology.

Analytic languages include some of the major East Asian languages, such as Chinese, and Vietnamese. Note that the ideographic writing systems of these languages play a strong role in regimenting linguistic continuity according to an analytic, or isolating, morphology.

Additionally, English is moderately analytic (probably one of the most analytic of Indo-European languages, while Afrikaans can be considered as the most analytic of all Indo-European languages). However, it is traditionally analyzed as a fusional language.

Synthetic languages

Synthetic languages form words by affixing a given number of dependent morphemes to a root morpheme. The morphemes may be distinguishable from the root, or they may not. They may be fused with it or among themselves (in that multiple pieces of grammatical information may potentially be packed into one morpheme). Word order is less important for these languages than it is for analytic languages, since individual words express the grammatical relations that would otherwise be indicated by syntax. In addition, there tends to be a high degree of concordance (agreement, or cross-reference between different parts of the sentence). Therefore, morphology in synthetic languages is more important than syntax. Most Indo-European languages are moderately synthetic.
