How to use plaintiff
Plaintiff is a formal legal term for someone who initiates a civil lawsuit, as opposed to a defendant who is sued. While it can also mean someone making a formal complaint more broadly, this usage is less common in modern English. It is distinctly different from criminal prosecution, where the state acts as the accuser rather than a private plaintiff.
Common phrases
- the plaintiff alleges

A common mistake
Learners sometimes confuse plaintiff with plaintive (meaning sad or mournful), which has a different etymology despite their similar spelling. Plaintiff and defendant are also confused in direction—the plaintiff brings the case against the defendant, not vice versa.
