Noun : In linguistics, a noun is a member of a large, open lexical category whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a prepositionhttp://en.wikipedia.org/wiki/Noun
verb : In syntax, a verb, from the Latin verbum meaning word, is a word (part of speech) that conveys action (bring, read, walk, run, learn), or a state of being(exist, stand). In most languages, verbs are inflected (modified in form) to encode tense, aspect, mood and voice. A verb may also agree with the person, gender, and/or number of some of its arguments,such as its subject, or object.

Adjective: In grammar, an adjective is a wordwhose main syntactic role is to modify a noun or pronoun, giving more information about the noun or pronoun's referent. Collectively, adjectives form one of the traditional English eight parts of speech,though linguists today distinguish adjectives from words such as determiners that also used to be considered adjectives.
