To Show
To Reveal
transitive verb, godan verb
This is the transitive version of 現れる (to appear), so rather than something appearing on its own, you’re making it appear. So this word means to show or to reveal, but it’s usually used in set phrases like 姿を現す (to show up) or 正体を現す (to reveal one's true nature).
Do you remember learning 現れる? This has the same exact pronunciation!
