2. a verb's time of action: Tense.
3. arrangement of verb forms by tense, voice, mood, person, and number: Conjugation.
4. a verb that functions as an adjective: Participle.
5. contains two or more main clauses: Compound Sentence.
6. specific noun to which a pronoun refers: Antecedent.
Explanation:
1. names something you cannot see or touch: Abstract Noun.
Examples: pain, joy, happiness, sympathy, arousal (they are all names of feelings, and feelings cannot be seen or touched, that is, they are abstract, as opposed to concrete).
2. a verb's time of action: Tense.
Example: I went to school yesterday. (the verb is "to go", which is in Simple Past Tense, meaning the action happens at a definite time in the past- in that particular sentence, "yesterday").
3. arrangement of verb forms by tense, voice, mood, person, and number: Conjugation.
Example: She has a bike. (Because the tense is Simple Present, the voice is active, the mood is indicative, the person is third and the number is singular, verb "to have" must be conjugated as "has" in the sentence above).
4. a verb that functions as an adjective: Participle.
Example: focused student ("focused" is the past participle of the verb "to focus", and it functions as an adjective, since it modifies the noun "student", that is, it works as a trait of that student).
5. contains two or more main clauses: Compound Sentence.
Example: Jill has a guitar and she plays the guitar every day. (There are two independente clauses here: "Jill has a guitar", whose subject is "Jill", and verb is "has", and "she plays the guitar every day", whose subject is "she", and verb is "plays". The two clauses are joined by the connective "and", which expresses addition).
6. specific noun to which a pronoun refers: Antecedent.
Example: Christine is nice and I help her do homework. ("Christine" is the proper noun which the object pronoun "her" refers to. Therefore, "Christine" is the antecedent in the sentence above).
