• 浅草あさくさ — Asakusa (place name)
• 浅瀬あさせ — shallow water / shoal
• 浅薄せんぱく — superficiality
• 浅知恵あさぢえ — shallow wisdom

The left side 氵 (sanzui) means water, and the right side 戋 contributes sound. Together, they describe something related to water that is not deep — hence “shallow.”

It also figuratively implies “not deep” in thinking, feeling, or even color shades.
