覗く
のぞく · nozoku · JLPT N3 · verb-godan
to peek in
👀 nozoku ≈ nose-poke: when you peek in, your nose pokes in first
Sound hook: no-ZO-ku sounds like nose-poke, and peeking in means poking your nose through a gap. The kanji 覗 also has 見 (to see) on its right side, so the character itself tells you this verb is about looking.
