linesperson
Court boundary judge
A linesperson is an official in sports like tennis, volleyball, and football who watches boundary lines to determine whether a ball or player is in or out of bounds.
The term is a gender-neutral alternative to linesman, which remains common in soccer and hockey for officials who assist the referee by monitoring offsides and other violations near the sidelines.
In a different context, a linesperson works for a utility company maintaining power or telephone lines.
