現れる
あらわれる · arawareru · JLPT N3 · verb-ichidan
to appear
👀 現 = jade 王 + see 見: when something appears, you can see it
The kanji 見 (to see) is inside 現, so 現れる means to come into view. You also find 現 in 現在 (now) and 現金 (cash): things that are present and real. For feelings showing on a face, Japanese often writes the same word as 表れる.
