alter the meaning of the main word. The added context only makes it more precise. As such, a "football" must be understood as a "ball". However, as is the case with "football", a well established compound word may have gained a special meaning in the language's vocabulary. Only this defines "football" as a particular type of ball (unambiguously the round object, not the dance party, at that), and also the game involving such a ball. Another example of special and altered meaning is "starfish" – a starfish is in fact not a fish in modern biology. Also syntactically, the compound word behaves like the main word – the whole compound word (or phrase) inherits the word class and inflection rules of the main word. That is to say, since "fish" and "shape" are nouns, "starfish" and "star shape" must also be nouns, and they must take plural forms as "starfish" and "star shapes", definite singular forms as "the starfish" and "the star shape", and so on. This principle also holds for languages that express definiteness by inflection (as in North Germanic). Because a compound is understood as a word in its own right, it may in turn be used in new compounds, so forming an arbitrarily long word is trivial. This contrasts to Romance languages, where prepositions are more used to specify word relationships instead of concatenating the words. As a member of the Germanic family of languages, English is unusual in that compounds are normally written in separate parts. This would be an error in other Germanic languages such as Norwegian, Swedish, Danish, German and Dutch. However, this is merely an orthographic convention: As in other Germanic languages, arbitrary noun phrases, for example "girl scout troop", "city council member", and "cellar door", can be made up on the spot and used as compound nouns in English too. Russian language In the Russian language compounding is a common type of word formation, and several types of compounds exist, both in terms of compounded parts of speech and of the way of the formation of a compound. Compound nouns may be agglutinative compounds, hyphenated compounds (стол-книга 'folding table', lit. 'table-book', "book-like table"), or abbreviated compounds (acronyms: колхоз 'kolkhoz'). Some compounds look like acronym, while in fact they are an agglutinations of type stem + word: Академгородок 'Akademgorodok' (from akademichesky gorodok 'academic village'). In agglutinative compound nouns, an agglutinating infix is typically
