Japanese 122 - Indicating ability with the potential form

In Japanese the ability to perform an action is expressed through conjugation of the verb, instead of by using auxiliary verbs like can and to be able to. This conjugation puts the verb into the potential form.

The potential form of all verbs ends in -る, and all potential forms are Group 2 verbs. Therefore, to convert a verb in potential form into -ます form, you simply replace the -る ending with -ます.

How the original verb is conjugated into the potential form depends on the verb group.

For verbs in Group 2, change the -る ending into -られる.

For verbs in Group 1, change the final う-sound into an え-sound, and add -る as ending.

When using the potential form, what in English would be the object, is the subject in Japanese. Therefore you will see the subject particle where you would expect the object particle .
