The term GOOSE SOUND can be broken down into two crossword solutions: HONK (4 letters) and CACKLE (6 letters). The sound of a goose is typically described as a HONK, which is a loud, low-pitched sound made by the bird. Geese are known to HONK when they are communicating with each other or when they feel threatened. Cackling is another sound that geese make, which is a higher-pitched sound than honking. This sound is usually made when geese are excited or happy.
