The word "唢呐" is formed through phonetic borrowing, where both characters "唢" and "呐" are used solely for their sound to transcribe the name of a musical instrument, specifically the suona, a double-reed horn. This disyllabic compound does not derive from the meanings of its individual components but instead approximates the instrument's pronunciation, likely originating from foreign language terms like the Persian "surnāy". Thus, the word is constructed as a phonetic imitation to designate the instrument.
