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 Russian word ''vídyat''/видят 'they see' has a morpheme per word ratio of 2:1, having two morphemes: the root ''vid-''/вид-, which conveys the imperfective aspect meaning, and the inflectional morpheme ''-yat''/-ят which inflects for four units of meaning (3rd

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

. 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.
