GrammarBook: い-adjective + すぎます (Too [adjective] / Excessively)

N4-G-041

い-adjective + すぎます (Too [adjective] / Excessively)

Supporting / Expressing Excess Quality

👀 Layer A: Visual Guide



📝 Quick Summary

This grammar pattern connects to the stem of an い-adjective (by removing the final い) to express that a quality or condition goes beyond a desirable, safe, or comfortable limit (e.g., too expensive, too spicy, too difficult).

Structure: [い-adjective (drop い)] + すぎます
Example 1: この ふくは たかすぎます (These clothes are too expensive).
Example 2: スープが あつすぎます (The soup is too hot).

🔗 Connected Grammar:

  • N4-G-040: Verb ます-form + すぎます (Too much action)
  • N4-G-042: な-adjective + すぎます (Too [na-adj])
  • N5-G-008: い-adjective Basics

🔍 Layer B: Deepening

💡 Raya’s Hack

The “II” Exception: よすぎます!
The most common trap with い-adjectives is the word いい (ii – good).
Because ii changes to yoi in conjugations, “too good” becomes よすぎます (yo-sugimasu), NOT ii-sugimasu!

– ❌ いいすぎます (Wrong)
– ⭕ よすぎます (Correct)

Example: この えいがは よすぎます! (This movie is too good!)

🚧 Joy’s Mistake

Scene: Joy is complaining about a bowl of spicy ramen.

Joy: 「この ラーメンは からい すぎます。」
(Kono raamen wa karai sugimasu.)

❌ Forgot to drop “い”!

Why?

Joy left the trailing i on karai. When combining い-adjectives with sugimasu, you MUST drop the final i to reveal the raw adjective stem (kara).

Correct: 「この ラーメンは からすぎます。」 (This ramen is too spicy.)
