Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

accūsātor, ōris, m. [id., prop. belonging to an accusation, hence], orig. one who calls another to account; hence, transferred to public life, an accuser, a plaintiff, esp. in a state-offence (while petitor signifies a plaintiff in private causes; yet accusator is often used for every kind of accuser, and then includes the petitor, v. accuso no. II. A.).
