โ ๏ธ Special Case: Vocal Cords
This is the ultimate curveball. Even though vocal cords are used to make sound and are often associated with music and singing, the correct spelling is vocal cords, not “vocal chords.” Why?

Many dictionaries do note “vocal chords” as a common variant, but “vocal cords” remains the standard, correct spelling in professional and academic writing.
