Attach the auxiliary verb すぎる to verb stems or adjective bases to express that an action or quality crosses an acceptable threshold, creating an unwanted excess.

Mental Model: Crossing the Threshold of Moderation
すぎる derives from the autonomous verb 過ぎる (to pass by / exceed). When attached as a suffix to another word, it means that an action or physical attribute has crossed the line of comfort, safety, or reason:
- The Emotional Tone: In standard Japanese, 〜すぎる carries a predominantly negative nuance of excess, discomfort, or regret: たくさん食べました = “I ate a lot (and I'm satisfied!).” vs 食べすぎました = “I ate too much (and now my stomach hurts!).”
Connection Formulas Across Word Classes
Attaching すぎる requires preparing the core stem of the word:
- Verbs (ます-stem + すぎる): Drop ます from the polite form and attach すぎる: 食べます → 食べすぎる (“eat too much”) · 飲みます → 飲みすぎる (“drink too much”) · 働きます → 働きすぎる (“overwork”).
- い-Adjectives (Drop い + すぎる): Remove the final い syllable and attach すぎる: 高い → 高すぎる (“too expensive / too tall”) · 辛い → 辛すぎる (“too spicy”) · 難しい → 難しすぎる (“too difficult”).
- な-Adjectives (Bare Stem + すぎる): Drop な and attach すぎる directly to the noun stem: 静か → 静かすぎる (“too quiet / eerily silent”) · 簡単 → 簡単すぎる (“too easy / trivial”).
- The Irregular Outlier: いい (Good) As with all conjugations, いい reverts to its classical root よい: drop い from よい → よすぎる (“too good / suspiciously good”).
Conjugating 〜すぎる as an Ichidan (Group 2) Verb
Once すぎる attaches to a stem, the entire compound functions grammatically as an Ichidan (Group 2) verb:
- Polite Present: 食べすぎます (“eat too much”)
- Polite Past: 食べすぎました (“ate too much”)
- Te-Form (Reason & Consequence): Using 〜すぎて is the most common way to explain why something went wrong: 昨日、飲みすぎて、頭が 痛いです。 (“Because I drank too much yesterday, my head hurts.”)
- Plain Past: 高すぎた (“was too expensive”)
