How to tell them apart
The same られる form carries two distinct roles: passive and potential. Passive describes an action done to a subject by someone else, as in このビルは建てられた (this building was built), where the subject receives the action. Potential describes whether someone or something can perform an action, as in 読めない (cannot read). The key test is agency: if the subject receives an action from another actor, it is passive; if the sentence expresses capability or possibility, it is potential. Swapping them changes the meaning entirely.
- られる Use られる passive when the subject receives an action done by someone else.
- られる Use られる potential when expressing whether an action can be performed.
