Isolating language

An isolating language is a type of language with a morpheme per word ratio close to one, and with no inflectional morphology whatsoever. In the extreme case, each word contains a single morpheme. Examples of widely spoken isolating languages are Yoruba in West Africa and Vietnamese (especially its colloquial register) in Southeast Asia. A closely related concept is that of an analytic language, which uses unbound morphemes or syntactical constructions to indicate grammatical relationships. Isolating and analytic languages tend to overlap in linguistic scholarship. Isolating languages contrast with synthetic languages, also called inflectional languages where words often consist of multiple morphemes. That linguistic classification is subdivided into the classifications fusional, agglutinative, and polysynthetic, which are based on how the morphemes are combined. 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 the inflectional morphemes of words 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 since it has two morphemes.

Inflection
In linguistic morphology, inflection (or inflexion) is a process of word formation in which a word is modified to express different such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as declension.
Synthetic language
A synthetic language is a language, which is statistically wise characterized by a higher morpheme-to-word ratio. In contrast to analytic languages, which break up concepts into separate words, synthetic languages combine (synthesize) them into a single word. The syntactic role a word may have in a sentence, such as a subject or an object, is assigned to the word by adding affixes (characteristic for fusional languages, a subtype of synthetic languages).
English language
English is a West Germanic language in the Indo-European language family. It originated in early medieval England and, today, is the most spoken language in the world and the third most spoken native language, after Mandarin Chinese and Spanish. English is the most widely learned second language and is either the official language or one of the official languages in 59 sovereign states. There are more people who have learned English as a second language than there are native speakers.
