Definition of the word petitioner

The word "petitioner" has its roots in Latin. It comes from the noun "petitus," which means "a praying" or "a begging," and the suffix "-er," which forms an agent or one who performs a particular action. In English, the word "petitioner" emerged in the 14th century and initially referred to someone who prayed or begged for something, often as a suppliant or a supplicant. Over time, the meaning of the word expanded to include anyone who submits a written request or plea to a governing body, court, or institution, usually with the intention of influencing a decision or outcome. Today, a petitioner is typically someone who files a petition, such as a lawsuit, application, or appeal, and is seeking a particular outcome or relief.
