1. Verb Groups/Classes:
* Verb Transitivity: This classifies verbs based on whether they require a direct object (transitive) or not (intransitive). For example:
* Transitive: "She wrote a letter." (letter = direct object)
* Intransitive: "The baby slept soundly." (no direct object)
* Verb Tense: This categorizes verbs based on their time reference (past, present, future). For example:
* Past: "He walked to school."
* Present: "She works at the library."
* Future: "They will eat dinner soon."
* Verb Voice: This describes the relationship between the subject and the action of the verb.
* Active Voice: The subject performs the action. "The dog chased the ball."
* Passive Voice: The subject receives the action. "The ball was chased by the dog."
* Verb Mood: This indicates the speaker's attitude toward the action.
* Indicative Mood: States a fact. "The sun shines."
* Imperative Mood: Gives a command. " Close the door."
* Subjunctive Mood: Expresses a wish, possibility, or hypothetical situation. "I wish I were rich."
2. Verb Phrases:
* These are groups of words that act as a single verb. For example:
* "She is going to the store." ("is going" is the verb phrase)
* "They have been working hard." ("have been working" is the verb phrase)
