Learn how to express that something was NOT a certain way in Japanese! This lesson focuses specifically on forming the negative past tense of adjectives to describe how things weren't in the past.

๐ŸŽฏ Learning Objectives


  • โ€ข Master the negative past tense patterns for both ใ„-adjectives and ใช-adjectives

The Two Types of Japanese Adjectives


Before learning the negative past tense, it's important to understand that Japanese has two main types of adjectives that conjugate differently:

1. ใ„-adjectives

These adjectives always end with the hiragana character ใ„ and conjugate by changing this ending.

  • โ€ข ใŠใ„ใ—ใ„ (delicious)
  • โ€ข ใŸใ‹ใ„ (expensive)
  • โ€ข ใ‚ใŸใ‚‰ใ—ใ„ (new)
  • โ€ข ใŠใ‚‚ใ—ใ‚ใ„ (interesting)

2. ใช-adjectives

These adjectives don't end with ใ„ (with a few exceptions) and conjugate by using forms of ใงใ™/ใ‚ใ‚‹.

  • โ€ข ใใ‚Œใ„ (beautiful/clean)
  • โ€ข ใ—ใšใ‹ (quiet)
  • โ€ข ในใ‚“ใ‚Š (convenient)
  • โ€ข ใ’ใ‚“ใ (healthy/energetic)

Negative Past Tense of ใ„-Adjectives


To say something "was not [adjective]," we need to use the negative past form. For ใ„-adjectives, we first change to the negative form (ใใชใ„), then make it past tense.

Pattern for Negative Past ใ„-Adjectives:

  • Step 1: Remove the final ใ„
    ใŠใ„ใ—ใ„ โ†’ ใŠใ„ใ—
  • Step 2: Add ใใชใ„ (to make it negative)
    ใŠใ„ใ— + ใใชใ„ โ†’ ใŠใ„ใ—ใใชใ„
  • Step 3: Change ใชใ„ to ใชใ‹ใฃใŸ (past negative)
    ใŠใ„ใ—ใใชใ„ โ†’ ใŠใ„ใ—ใใชใ‹ใฃใŸ
  • Step 4: For polite speech, add ใงใ™
    ใŠใ„ใ—ใใชใ‹ใฃใŸ โ†’ ใŠใ„ใ—ใใชใ‹ใฃใŸใงใ™

More Examples:

  • ใŸใ‹ใ„ โ†’ ใŸใ‹ใใชใ„ โ†’ ใŸใ‹ใใชใ‹ใฃใŸใงใ™

    was not expensive

  • ใ‚„ใ•ใ—ใ„ โ†’ ใ‚„ใ•ใ—ใใชใ„ โ†’ ใ‚„ใ•ใ—ใใชใ‹ใฃใŸใงใ™

    was not easy/kind

  • ใ•ใ‚€ใ„ โ†’ ใ•ใ‚€ใใชใ„ โ†’ ใ•ใ‚€ใใชใ‹ใฃใŸใงใ™

    was not cold

Using in Sentences:

  • ใใฎใˆใ„ใŒใฏใŠใ‚‚ใ—ใ‚ใใชใ‹ใฃใŸใงใ™ใ€‚

    That movie was not interesting.

  • ใใฎใ†ใฏใ•ใ‚€ใใชใ‹ใฃใŸใงใ™ใ€‚

    Yesterday was not cold.

  • ใ“ใฎใปใ‚“ใฏใ‚€ใšใ‹ใ—ใใชใ‹ใฃใŸใงใ™ใ€‚

    This book was not difficult.

Negative Past Tense of ใช-Adjectives


For ใช-adjectives, the negative past form follows a different pattern. Instead of changing the adjective itself, we use ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ after the adjective.

Pattern for Negative Past ใช-Adjectives:

  • Step 1: Take the basic form of the ใช-adjective
    Example: ใใ‚Œใ„ (beautiful/clean)
  • Step 2: Add ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ
    ใใ‚Œใ„ + ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ โ†’ ใใ‚Œใ„ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ

Formal vs. Casual: ใงใฏ vs. ใ˜ใ‚ƒ

Formal (ใงใฏ):

  • โ€ข ใใ‚Œใ„ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ
  • โ€ข ในใ‚“ใ‚Šใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ
  • โ€ข Use in: business settings, with teachers, with strangers, in writing

Casual (ใ˜ใ‚ƒ):

  • โ€ข ใใ‚Œใ„ใ˜ใ‚ƒใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ
  • โ€ข ในใ‚“ใ‚Šใ˜ใ‚ƒใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ
  • โ€ข Use with: friends, family, casual conversations

In this course, we'll focus on the formal ใงใฏ form, but it's important to recognize the ใ˜ใ‚ƒ form when you hear it in everyday conversations, TV shows, or anime.

More Examples:

  • ใ—ใšใ‹ โ†’ ใ—ใšใ‹ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ

    was not quiet

  • ในใ‚“ใ‚Š โ†’ ในใ‚“ใ‚Šใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ

  • ใซใŽใ‚„ใ‹ โ†’ ใซใŽใ‚„ใ‹ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸ

    was not lively

Using in Sentences:

  • ใใฎใƒฌใ‚นใƒˆใƒฉใƒณใฏใใ‚Œใ„ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸใ€‚

  • ใใฎใƒ‘ใƒผใƒ†ใ‚ฃใƒผใฏใซใŽใ‚„ใ‹ใงใฏใ‚ใ‚Šใพใ›ใ‚“ใงใ—ใŸใ€‚

    That party was not lively.
