The term "junior miss" refers to a young girl who falls within the range of around 12 to 15 years old. While this is a commonly used term, there are various synonyms that can be used to refer to a young girl of this age. Some potential alternatives include "teenager", "pubescent", "adolescent", "youth", "maiden", "youngster", "miss", or simply "young girl". Each of these synonyms offers a slightly different connotation or emphasis, but all can be used to describe a young girl who is not yet considered a full adult.
