Homonym: Croak (Sound)
"Croak" refers to the sound made by certain animals, particularly frogs and toads. This vocalization is produced by the vibration of vocal cords and is often used for communication, especially during mating season. The sound can vary in pitch and intensity depending on the species and the context in which it is made.
In addition to its biological meaning, "croak" is also a colloquial term for dying. This usage likely stems from the association of the sound with the end of life, as many people connect the croaking of frogs with the natural cycle of life and death in ecosystems.
