Explanation

Although historically languages were divided into three basic types (''isolating'', ''inflectional'', ''agglutinative''), the traditional morphological types can be categorized by two distinct parameters: * morpheme per word ratio (how many morphemes there are per word) * degree of fusion between morphemes (how separable words' inflectional morphemes are according to units of meaning represented) A language is said to be more isolating than another if it has a lower morpheme per word ratio. To illustrate the relationship between words and morphemes, the English term "rice" is a single word consisting of only one morpheme (''rice''). This word has a 1:1 morpheme per word ratio. In contrast, "handshakes" is a single word consisting of three morphemes (''hand'', ''shake'', ''-s''). This word has a 3:1 morpheme per word ratio. On average, words in English have a morpheme per word ratio substantially greater than one. It is perfectly possible for a language to have one inflectional morpheme yet more than one unit of meaning. For example, the

subject, present/future tense, indicative mood). Effectively, it has four units of meaning in one inseparable morpheme: ''-yat''/-ят. Languages that are relatively more isolating have a morpheme per word ratio that approaches 1:1. A purely-isolating language would lack any visible morphology since no word would have an internal compositional structure in terms of word pieces (i.e. morphemes) and so it would lack bound morphemes like

affixes In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English ''-ness'' and ''pre-'', or inflectional, like English plural ''-s'' and past tense ''-ed''. They ...

. The morpheme per word ratio is a scalar category ranging from low ratios (approaching 1:1) on the isolating hypothetical pole of the scale, to a high morpheme per word ratio. The greater the overall ratio, the less isolating and the more synthetic the language.
