Verb Conjugation #6: Easy/Hard to Do
To state that something is easy to do, add やすい to the masu stem of the appropriate verb.
You can do the same thing with にくい in place of やすい to say that something is difficult.
This lesson is simple, and so there is not much to add to the main points above.
The first step is to get the masu stem of a verb. To do this, just remove ます from the polite form of the verb (e.g., the polite form of 読む (よむ) (to read) is 読みます. So, the masu stem of this verb is 読み.
From there, add either やすい to express that the action is easy to perform or にくい to express that it is hard. For example, 読みやすい means "easy to read," while 読みにくい means "hard to read."
Note that standard practice is to write やすい and にくい in kana, not using the kanji 安い or 難い.
