Which word describes a light meal or snack in English?

The term that describes a light meal or snack in English is "tentempié." This word is derived from Spanish, where it is used to refer specifically to a snack or a small meal that is typically eaten between larger meals. In English, the equivalent terms would be "snack," "light meal," or "treat," used to describe something light and not substantial enough to be considered a full meal.

When considering the context of the other terms, they do not relate to the concept of a light meal or snack. "Rest" refers to a state of relaxation or cessation of activity, while "route" pertains to a path or direction taken to reach a destination. "Calm waters" is a phrase that suggests tranquility, often used in a metaphorical context, but does not pertain to food or meals. Thus, "tentempié" is the only option that correctly captures the idea of a light meal or snack.
