Classes of Verbs - Transitive, Intransitive and Linking

    Transitive verbs have direct objects. NOTE: If you can say what or who after the verb, it is transitive.

    Intransitive verbs do not take an object.
    The models drank before the show. (before is not an object)
    Linking verbs join words and are either forms of the verb to be or sensory verbs such as feel, smell, sound and taste. Other verbs that are linking are those that cannot actually be seen and include seem, appear, became, grow, look, seem, remain and stay.

MOODS - Indicative, Imperative and Subjunctive

    The indicative mood is used to ask questions or state facts.
    He was not pleased with the outcome of the meeting.
    Was he pleased with the outcome of the meeting?
    The imperative mood is for requests and to give instructions and can include or have the implied inclusion of the word please.
    Can you come to the meeting next week.
    Please can you come to next week's meeting. NOTE: No question marks are used in these examples as they are considered indirect instructions.
    The subjunctive mood is one of the most misused forms. Because it is not generally used in the spoken language, it is not used (unfortunately) in the written language.
    The following are examples of incorrect and correct usage::
    The request was that the rules are followed. (incorrect)
    Should be "The request was that the rules be followed." (correct)

VOICE - Active and Passive

    When the subject of the sentence does the action, the voice is active. When the subject receives the action, the verb is in passive voice.
    Active voice: James published the booklets.
    Passive voice: The booklets were published by James.

GERUNDS - verbs used as nouns
