Discessisti

Discessisti is a Latin verb form meaning “you departed” or “you have departed.” It is the second-person singular perfect indicative active of the verb discedere, “to depart” or “to withdraw.” The form is built from the present stem disced-, plus the perfect tense ending -isti.

Morphology and related forms: The principal parts of discedo are discedo, discedere, discessi, discessum. From these, the perfect active forms include discessi (I departed), discessisti (you departed), discessit (he/departed), discessimus (we departed), discessistis (you all departed), and discesserunt (they departed). Discessisti thus denotes a completed action by the subject in the past and is typically found in narrative or historical Latin. The corresponding non-personal forms include discessus (a departure) and related participles such as discessum.

Usage and nuance: Discessisti is used when the subject is in the second person and the action is viewed as completed. In Latin prose, pronouns such as tu (you) are often implicit in the verb ending, but an explicit tu can appear for emphasis: Tu discessisti. The form contrasts with discessit (third-person singular) and with other persons and tenses of discedere.

In reception: Discessisti is regularly encountered in classical Latin texts, as well as later medieval and ecclesiastical Latin, wherever a narrator records that “you departed.” It is primarily of interest for Latin verb conjugation, syntax, and historical meaning rather than as a standalone lexical item.
