youngster

This term carries a distinct social dynamic, often implying a gap in experience or status between the speaker and the subject. It is frequently used by older adults to refer to children or adolescents, sometimes with a sense of nostalgic affection or, conversely, a patronizing tone that emphasizes the subject's perceived immaturity.

While it refers to a person, the word is used as a standard countable noun. It does not possess the irregular pluralization found in collective nouns or the mass-noun properties of abstract concepts, following standard English pluralization rules.
