yes

This word serves as the primary marker of affirmation in English. While it is most commonly used as a standalone particle to answer questions, it carries a tone of certainty and agreement that can range from polite compliance to enthusiastic endorsement depending on the prosody.

When used as a noun, the word refers to the specific act of voting or consenting. In this capacity, it follows standard countability rules for a response, allowing it to be pluralized when referring to a collection of affirmative votes in a formal tally.
