Constant

Political thinker's surname

Constant describes something that doesn't change or stop.

A constant temperature remains steady.

Constant noise continues without interruption.

Constant complaints come one after another.

As a noun, a constant is something that stays the same while other things vary—in math, a fixed value; in life, a reliable presence: Coffee has been my one constant through grad school.

To be constant to someone is to remain faithful or loyal, though this use sounds old-fashioned.
