Rookie

Rookie refers to a person who is new to a particular field, organization, or activity, typically during their first season or year. The term entered American slang in the late 19th or early 20th century; the exact origin is uncertain, but it is commonly thought to derive from recruit or newcomer.

In sports, a rookie is a first-year player. Teams evaluate their skills and potential, often tracking development over the season. Many leagues award a Rookie of the Year honor to the top performing first-year player. Related concepts include rookie contracts, which set entry-level terms, and the hobby use of rookie cards for an athlete's first trading card. The phrase rookie mistakes refers to common errors made by beginners as they adjust to professional demands.

Outside sports, rookies are new employees in workplaces, new recruits in the military, and debuting artists or performers in entertainment. In esports and online gaming, rookie divisions or classifications are used for newer competitors.

The label emphasizes learning, growth, and the learning curve associated with moving from novice to more experienced status. While the status is temporary, it can influence media attention, mentorship opportunities, and team expectations as individuals accumulate experience and evidence of capability.
