1. A mental state that arises spontaneously rather than through conscious effort and is often accompanied by physiological changes; a feeling: the emotions of joy, sorrow, and anger.
2. Such mental states or the qualities that are associated with them, especially in contrast to reason: a decision based on emotion rather than logic.
[French émotion, from Old French, from esmovoir, to excite, from Vulgar Latin *exmovēre : Latin ex-, ex- + Latin movēre, to move; see meuə- in the Appendix of Indo-European roots.]
