The word "莺歌" is formed from the character "莺", meaning oriole, constructed with the radical "艹" for vegetation and "鸟" for bird, indicating a bird associated with grassy areas, and the character "歌", meaning song, composed of "欠" for breath and "可" for sound, representing the act of singing. Combined, they create a compound where "莺" denotes the bird and "歌" denotes its action, literally meaning "oriole's song".
