What does kitten mean?
A kitten is a young cat, especially one that is still small and developing. The word is commonly used for newborn cats, playful kittens, and young cats that have not yet reached full adulthood. It also has an affectionate or humorous use as a term for a young woman or girl, although that sense can sound dated or patronizing depending on how it is used. In everyday speech, “kitty” is often the more informal alternative, especially when speaking directly to a young cat or expressing affection. “Kitten” is also part of several common expressions, including “a litter of kittens,” “a mother cat with kittens,” and “kitten food.” Its diminutive origin reflects the animal’s small size and tender appearance, while its modern usage remains both literal and affectionate.
