やすい (yasui)
~やすい — easy to ~, tends to ~
Pattern
-
動詞ます形(語幹) + やすいstem + やすい (読む → 読みやすい)
Two meanings
The first is “easy to do because of the nature of the thing”: 読みやすい本, 分かりやすい説明. The second is a tendency, often an unwelcome one: 事故が起きやすい (accidents tend to happen), 風邪をひきやすい (catch a cold easily).
Conjugation
Because it ends in い, it conjugates as an い-adjective: 読みやすかった, 読みやすくない, 読みやすくて. It can modify a noun directly: 読みやすい本.

この本(ほん)は字(じ)が大(おお)きくて読(よ)みやすいです。

Common mistakes
- Use the stem: 読みやすい, not 読むやすい.
- The thing that is easy to do is the subject: この本は読みやすい. The subject is not the person who reads.
