【The difference】between と (to), ば (ba) and ら (ra)



と, ば and ら are used in the sentence pattern below:

Sentence 2 + if or when + Sentence 1

Sentence 1 + と, ば or ら + Sentence 2

The difference amongst と, ば and ら

If ‘Sentence 1’ happens, ‘Sentence 2’ also happens repeatedly or constantly without fail. This is the basic rule of と.

For example, と is used to describe what happens in nature, habit, how a machine operates etc.

ば basically follows the rule of と, but it can be used when you describe what happens only once. (not repeatedly or constantly)

ら is close to ば. It is used when you describe what happens once.

A sentence with ら is usually not changeable into a sentence with と.


We are going to the sea if it is sunny tomorrow.

Correct: あしたはれた私たちは海に行きます。

Correct: あしたはれれ私たちは海に行きます。

Incorrect: あしたはれる私たちは海に行きます。

The difference amongst those three is not big. Japanese people would understand you even if you use と incorrectly when ら should be used.

Don’t worry about making mistakes too much. It is recommended that you use it, then you would get used to how to use them.

People would also correct your Japanese to help you to improve your Japanese.


と and ら can also be used as ‘then’ or ‘after that’.
