What does babyish mean?
Babyish is an adjective used to describe qualities, behaviors, or appearances that resemble those of a baby — such as softness, helplessness, babbling, or thumb-sucking — or to characterize someone as acting more childish and immature than their age warrants. The word sits on a spectrum with related terms: 'childish' broadly evokes childhood immaturity at any stage of growing up, while 'babyish' points more narrowly to the earliest stage of infancy. When applied to children, it is usually descriptive and neutral, noting a lingering infantile trait like a babyish voice. When applied to adults or older children, however, it tends to carry a mildly disapproving tone, implying that someone should have outgrown the behavior in question. Common contexts include discussions of speech patterns, emotional outbursts, handwriting, facial features, and habits.
