The back  of a ship  also provides the pronunciation

About

The character is a specialized nautical term for the stern or rear section of a ship. It is a phono-semantic compound: the left component , the 'boat' radical, establishes the semantic field of watercraft and navigation. The right component (wěi, 'tail') functions both as the phonetic indicator, determining the pronunciation, and as a semantic clue, since the stern of a vessel is akin to a tail. The combination of boat and tail thus directly conveys the idea of a ship's back end.
