TERMS DESCRIBING PARTS OF SPEECH SENTENCE: A sentence is a complete thought that contains a subject and a verb: The secretary typed the letter. SUBJECT: The subject is the noun (person, place, or thing) involved in the action of the verb: The SECRETARY typed the letter. VERB: The action word affecting the subject: The secretary TYPED the letter. ADVERB: A word that describes a verb, an adjective, or another adverb: The secretary QUICKLY typed the letter. ADJECTIVE: A word that describes a noun: The secretary quickly typed the LONG letter. MODIFIER: Any word, phrase, or clause that furnishes information about another word or word grouping within the same sentence. The adverb and adjective capitalized below are also known as modifiers: The secretary QUICKLY typed the LONG letter. NOUN: A person, place, or thing: The SECRETARY quickly typed the long LETTER. PRONOUN: A word that is substituted for another word (usually a noun) to avoid unnecessary repetition: The secretary hummed a tune as HE quickly typed the long letter. ANTECEDENT: The word to which a pronoun refers: The SECRETARY hummed a tune as he quickly typed the long letter. OBJECT: A noun or pronoun acted upon by a verb: The secretary hummed a TUNE as he quickly typed the long LETTER. PREPOSITION: A word that generally establishes the location of a noun or pronoun: The secretary carried the letter ACROSS the hallway. OBJECT of the PREPOSITION: The noun or pronoun that follows the preposition: The secretary carried the letter across the HALLWAY. COORDINATING CONJUNCTION: A word that links other words or word groupings together: The secretary carried the letter to his boss, AND she read it. PARENTHETICAL EXPRESSION: An expression that interrupts the flow of a sentence to provide a transition, interjection, explanation, or cause and effect relationship: The secretary carried the letter to his boss, who was very busy; NONETHELESS, she read it. TERMS DESCRIBING WORD GROUPINGS INDEPENDENT CLAUSE: Another term for a sentence that is complete and can stand alone: The secretary carried the letter to his boss. DEPENDENT CLAUSE: An incomplete thought, usually introduced by a word such as "which," "when," "who," "what," "how," or "that." A dependent clause must be linked to an independent clause to produce a complete sentence: WHEN THE SECRETARY HAD FINISHED TYPING THE LETTER, he carried it to his boss. NOTE: The first clause in the preceding sentence is an incomplete thought and depends upon the second clause to complete the sentence. PHRASE: Similar to a dependent clause, except that a phrase does not contain both a subject and a verb. The following are the four most common types of phrases: 1. A PREPOSITIONAL PHRASE is a word grouping introduced by a word that normally establishes the location of a noun (over the hill, around the corner, between acts, etc.). 2. An INFINITIVE PHRASE is a word grouping introduced by the word "to" plus a verb (to run fast, to try harder, etc.). 3. A PARTICIPIAL PHRASE is a word grouping introduced by a verb with an "-ing" or "-ed" ending (reading a book, stopped for a red light, etc.). 4. An APPOSITIVE PHRASE is a word grouping that renames or relabels a noun: Denise, AN INTELLIGENT WOMAN, has earned her degree in comparative literature. SIMPLE SENTENCE: A sentence consisting of one independent clause: The secretary typed the letter. COMPLEX SENTENCE: A sentence consisting of an independent clause and one or more dependent clauses: When the secretary had finished typing the letter, he carried it to his boss. COMPOUND SENTENCE: A sentence consisting of independent clauses that are linked together by a coordinating conjunction and/or appropriate punctuation: The secretary carried the letter to his boss, and she read it. The secretary carried the letter to his boss; she read it and told him it was perfect.
