To Be Hidden
intransitive verb, ichidan verb
隠す is "to hide." 隠れる is to be hidden. You know that this is the version where something is hidden (and you're not doing the hiding) because it is rare (れる) that you ever find something that has been hidden (not by you).
The reading is the same as 隠す. So as long as you know that you know this as well.
