The word "送殡" is formed by combining the character "送", meaning to escort, constructed from the radical "辵" indicating movement and the phonetic component "关" suggesting pronunciation, with the character "殡", meaning funeral, built from the radical "歹" denoting death and the phonetic component "賓" providing sound; together they create a compound word where "送" conveys the action of escorting and "殡" specifies the funeral context, resulting in the meaning of attending a funeral or accompanying a coffin to the grave.
