cranky

"Cranky" describes someone who is in a bad mood and easily irritated. It suggests a level of grumpiness that goes beyond simple sadness or tiredness—it's a more active disposition to be annoyed, like you might snap at small things.

While often used to describe children (a cranky baby needing a bottle!), adults can absolutely be cranky too. A long flight delay, a frustrating work project, or even just waking up on the wrong side of the bed can all lead to a cranky mood.

It's important to note that "cranky" isn't usually used for serious depression or prolonged sadness; it implies a temporary state of irritability. You might say, "He was a little cranky this morning because he didn't get enough sleep," or "She gets cranky when she's hungry."

Sometimes, "cranky" can even describe things causing irritation! An old, unreliable machine might be called "cranky," suggesting it's prone to breaking down and causing frustration. So whether describing a person's mood or an object's behavior, "cranky" signals something is off-kilter and likely to cause annoyance.
