Quits is most commonly encountered as the third-person singular present tense of the verb quit, meaning to stop doing something, to leave a job, or to abandon a habit. The base form is quit; present tense forms are quit (I quit, you quit, we quit) and quits (he quits, she quits). The present participle is quitting, and the simple past and past participle are quit.

As a noun, quit is rare and largely historical or legal in tone. In older or specialized usage, the phrase be quits can mean to owe nothing or to be even after a settlement. In modern everyday English, the noun sense is infrequent and typically replaced by terms such as cessation, discharge, or settlement.

Etymology: quit descends from Old French quitter, meaning to leave or depart, which in turn derives from Latin quietus, meaning at rest or freed from obligation. Over time, the verb sense broadened to include ceasing an activity, resigning, or abandoning a habit.

In other contexts, quit appears in computing and user interfaces as a standard command or menu option to exit an application or document. The word also features in common collocations and phrases such as quitting a job, quitting smoking, or quitting an activity, reflecting its broad semantic field related to cessation and departure.
