Main ideas / lessons about imperative sentences (명령문)

  1. Definition

    • An imperative sentence is used to give:
      • a command
      • advice
      • counsel
    • The “imperative” portion is essentially the command/action directive aimed at another person.

  2. Types of imperatives

    • Positive imperative
      • Starts with the base form of the verb (verb stem).
      • The subject is omitted (implicitly understood as “you”).
    • Negative imperative
      • Uses don’t + base form of the verb.
      • The visible subject is still omitted.

  3. Politeness in imperatives

    • Adding please (placed before or after the relevant element) makes the imperative feel like a polite request/suggestion instead of a harsh command.

  4. Negation details

    • For negative imperatives, the core pattern is:
      • don’t + verb (base form)
    • Extra adverbs/adjectives may appear after the verb phrase to refine meaning, e.g.:
      • Don’t be late again
    • The lecture emphasizes that the “don’t + base form” structure is the intended one (i.e., negating “doesn’t” doesn’t map to this pattern via forms like “didn’t / …”).

  5. Important exam point: imperatives + punctuation/conjunction markers

    • A major exam topic is what happens when an imperative is followed by certain connectors/markers after a comma.
    • Core rule taught:
      • After the imperative, decide what the next clause expresses:
        • Positive result/content → connect with &
        • Negative result/content → connect with May (as the lecture’s transcription-equivalent to a negative linkage like “otherwise/but/if not”)
    • The lecture repeatedly stresses that:
      • The meaning of what comes after the comma determines whether the linkage is treated as positive or negative.

  6. Meaning distinction example (direction type)

    • Direction-like sentences can look similar, but differ in the result meaning:
      • “Turn right, then you will see the building.”
        • Interpreted as a positive result after the comma → use the positive linkage logic.
      • “Turn right, or otherwise you will miss it.”
        • Interpreted as a negative result after the comma → use the negative linkage logic.
    • Key point: even if the grammar looks similar, the connector choice changes with the result content.

  7. Problem-solving approach taught

    • For imperative-combination exam questions:
      • First, identify the imperative form (positive or negative).
      • Then, check what comes after the comma.
      • Classify the result as positive or negative.
      • Apply the connector rule:
        • & for positive result
        • May for negative result (per the lecture’s convention)
    • The lecture warns it can feel confusing, but the rule works when applied based on meaning.

  8. Additional examples of applying the rule

    • Umbrella / soaked example (content-based negative result)
      • Imperative: “Take the umbrella…”
      • Result: “otherwise you will get completely soaked” (negative outcome)
      • Therefore, use the negative-result connector logic.
    • Cold prevention example (surface negation ≠ result meaning)
      • If the second clause is “you won’t catch a cold,” treat it as:
        • not catching a cold = positive result (prevention)
      • So it can use the positive-result connector rule,
        • even though the surface form contains “won’t.”
    • The lecture highlights this as very important, noting common confusion.

Methodology / instructions (bullet format)

  • Step 1: Determine imperative type

    • Positive command: write the verb base form (subject omitted: implicit “you”).
    • Negative command: write don’t + verb base form.

  • Step 2: If “please” is present

    • Interpret it as making the imperative more polite/request-like.

  • Step 3: If there is a comma after the imperative, check what follows

    • Determine whether the clause after the comma expresses:
      • positive result/content
      • negative result/content
    • Use connector choice according to the lecture:
      • positive result → “&”
      • negative result → “May”

  • Step 4: Handle tricky “won’t” / negative-meaning cases

    • Classify based on result meaning, not only surface negation:
      • “won’t catch a cold” is treated as positive result (cold prevention) → use the positive-result connector.

  • Step 5: For exam problems

    • Always read the second clause for outcome meaning, then choose the correct connector accordingly.
