しんどい

shindoi

tired; exhausted

Word type: I-adjectives

Standard: くたびれる

Example:

今週、残業ばっかりでめっちゃしんどいわ。
I've been working overtime all week. I'm so exhausted.

Commentary:

While both しんどい and えらい can mean "tired", しんどい is more commonly used.

In addition, えらい can express degree, while しんどい can not. For example, one could say えらいしんどい (very tired), but could not say しんどいえらい.
