英語は名詞と動詞によって s をつけたりつけなかったり。
今日はLinda先生が解説してくれました！！

Hello everyone! This is Linda-sensei!

Today I want to remind everyone to be careful with using the correct part of speech. Recently, in one of my classes we used "work" and "works" but my student was confused about when adding "s" is okay.
As a noun, work refers to your job which is uncountable so you can not add "s" but as a verb, it has to agree with the subject.
