The Japanese adverb 'ぐるぐる' describes a circular or spinning motion. It is often used to depict something turning, rotating, or moving in circles. This word can be applied to physical movements, such as spinning objects, or abstract concepts, like thoughts going in circles. For example: the fan is spinning round and round「扇風機がぐるぐる回っている」(せんぷうきがぐるぐるまわっている). My head is spinning「頭がぐるぐるする」(あたまがぐるぐるする). Additionally, 'ぐるぐる' can imply repetition or going around something, as in wrapping a scarf around your neck「マフラーをぐるぐる巻く」(マフラーをぐるぐるまく).
