careful enquiry, headstrong
聽 centers on attentive listening and careful examination, but the given meanings also include 'headstrong', which seems contradictory. The core idea may be a focused, perhaps stubborn, inquiry—listening intently or investigating with determination.
聽 is the traditional form of 聴. It combines 耳 (ear) with a phonetic component that includes 王, 十, 罒, and 心, suggesting listening with attention or mental focus. The exact historical development of the right side is complex and uncertain.
The left side is an ear 耳, and the right side contains a heart 心 under a net-like shape 罒 with a cross 十 and a king 王 above. Imagine a king listening carefully through a net of thoughts, his heart stubbornly set on hearing every detail.
For チョウ, picture a stubborn chief named Chou who insists on listening to every report himself: Chou -> チョウ, and his ear is always open.
