"Nay" is an old-fashioned word used to mean "no." It is often found in literature, speeches, and formal contexts. People might use "nay" to express disagreement or to reject a proposal. The term is commonly associated with voting, where members may say "yea" for yes and "nay" for no. In addition to its use in language, "Nay" can also refer to a sound made by horses. This sound is a vocalization that horses use to communicate with each other and their handlers. The word captures the essence of a horse's call, often described as a neigh.
