The word "海曙" is formed by combining the character "海", meaning sea, which itself is a pictophonetic character composed of the water radical "氵" to indicate its semantic field and the component "每" to suggest its pronunciation, with the character "曙", meaning dawn, also a pictophonetic character composed of the sun radical "日" for its semantic aspect and the component "署" for its phonetic cue, resulting in a compound that literally denotes the concept of a sea dawn.
