Forfeit is usually defined as the act of quitting in a sports game or sometimes, charging a person with a fine over a late payment, etc.
In this post, I will add two sentences, using them in two different ways.
a.) Unfortunately, one of the best softball teams forfeited (quitted) due to a low number of players showing up for the game.
b.) After two days have passed the housing payment deadline, a woman was forfeited (charged) with a late fee.
How would you define “forfeit” and what sentences can you use this term?
