What does grouchy mean?
Grouchy is an informal word for someone who is easily annoyed, bad-tempered, and inclined to complain. It often suggests a recurring or characteristic mood rather than a single moment of irritation: a person may be called grouchy after repeatedly sighing, criticizing, or finding fault. The adjective can be used in serious conversation, but it is especially common in light, humorous, or child-friendly contexts, such as descriptions of cantankerous animals or fictional characters. The word can also function as an informal noun for a habitual complainer, although this use is less frequent. Grouchy is milder and more conversational than words such as irascible, cantankerous, or choleric. It remains useful in ordinary English because it captures not merely anger but the combination of impatience, dissatisfaction, and verbal complaint that characterizes a recognizable type of person.

Where does grouchy come from?
Grouchy was formed in mid-19th-century English by adding the suffix -y to grouch, a word associated with complaining or grumbling. Grouch itself was already in use in the early 19th century, although its more remote ancestry is uncertain, making the English derivation better established than claims connecting it with a particular earlier language. The resulting adjective could describe a habitual state, while the noun use came to denote a person who is characteristically grouchy.
