IPA: /ˈtwiːnər/
KK: /ˈtwiːnər/
A person or thing that fits between two categories or roles, often used in sports or computing contexts.
The coach decided to use him as a tweener because he could play both forward and guard positions effectively.
The word 'tweener' is derived from 'tween' (a colloquial contraction of 'between', meaning in the middle) and the suffix '-er' (meaning a person who). A 'tweener' refers to a person or thing that is in between two categories or stages.
Think of someone who is 'in between' ('tween') two different ages or stages, and the '-er' indicates that this person is defined by that position.
