which qualify nouns and pronouns, and adverbs, which mainly modify verbs, adjectives, or other adverbs. Not all languages make this exact distinction; many (including English) have words that can function as either. For example, in English, fast is an adjective in "a fast car" (where it qualifies the noun car) but an adverb in "he drove fast" (where it modifies the verb drove). In Dutch and German, adjectives and adverbs are usually identical in form and many grammarians do not make the distinction, but patterns of inflection can suggest a difference: A clever new idea. A cleverly developed idea. A German word like ("clever(ly)") takes endings when used as an attributive adjective but not when used adverbially. (It also takes no endings when used as a predicative adjective: , "he is clever".) Whether these are distinct parts of speech or distinct usages of the same part of speech is a question of analysis. It can be noted that, while German linguistic terminology distinguishes from , German refers to both as ("property words"). Determiners Linguists today distinguish determiners from adjectives, considering them to be two separate parts of speech (or lexical categories). Determiners formerly were considered to be adjectives in some of their uses. Determiners function neither as nouns nor pronouns but instead characterize a nominal element within a particular context. They generally do this by indicating definiteness (a vs. the), quantity (one vs. some vs. many), or another such property. Adjective phrases An adjective acts as the head of an adjective phrase or adjectival phrase (AP). In the simplest case, an adjective phrase consists solely of the adjective; more complex adjective phrases may contain one or more adverbs modifying the adjective ("very strong"), or one or more complements (such as "worth several dollars", "full of toys", or "eager to please"). In English, attributive adjective phrases that include complements typically follow the noun that they qualify ("an evildoer devoid of redeeming qualities"). Other modifiers of nouns In many languages (including English) it is possible for nouns to modify other nouns. Unlike adjectives, nouns acting as modifiers (called attributive nouns or noun adjuncts) usually are not predicative; a beautiful park is beautiful, but a car park is not "car". The modifier often indicates origin ("Virginia reel"), purpose ("work clothes"), semantic patient ("man eater") or semantic subject ("child actor"); however, it may generally indicate almost any semantic relationship.
