冒険
ぼうけん · bouken · JLPT N3 · noun
hazard
🧭🗺️ 冒険 = dare (冒) + steep danger (険): to brave the danger
冒 means to brave or risk something, as in 冒す (okasu, to risk). 険 means steep or perilous, as in 危険 (kiken, danger). Put them together and you get someone choosing to go into danger, which is what an adventure is.
冒 — top 冃 (cloth/cover) + 目 (eye)
Originally a pictograph showing a cloth or cap covering the eyes, suggesting something pulled down over the head. From this came the meaning 'to cover,' then by extension 'to risk' or 'brave through' (as in pushing forward despite obstacles). The top component 冃 is often miswritten as 日, but it depicts a covering, not the sun.
