The word "mu" is an interjection in Spanish.
/mu/
The most common translation of "mu" into English is "moo," which is the sound that cows make.
In Spanish, "mu" is primarily recognized as an onomatopoeic word representing the sound a cow makes. It is often used in a playful or childish context, making it frequent in conversations involving children or in literature directed at young audiences. The word is more commonly used in oral speech than in written context, particularly in children's stories, songs, or games.

While "mu" itself is not commonly found in many idiomatic expressions, it plays a supportive role in playful or childish sayings, particularly those that engage with farm life or animals.
"Careful, here comes the 'moo.'" (Used in children's games to signal the approach of something or someone.)
"Pinta la vaca, que suena 'mu'."
"Paint the cow, because it goes 'moo.'" (A playful instruction in an arts and crafts context for children.)
"En la granja todos dicen 'mu'."
The word "mu" is onomatopoeic in nature, derived directly from the sound made by cows. This usage can be traced to early human interactions with livestock, where sounds made by animals were often mimicked in language.
There are no direct antonyms for "mu," as it is an onomatopoeic expression without opposing sounds. However, one could consider the sounds made by other animals as contrasting expressions, like "piar" (chirp for birds) or "ladrar" (bark for dogs).
