Which word describes a meal or food served for consumption?

The word "repast" specifically refers to a meal or food served for consumption. It originates from the Latin word "repaastus," which means to break bread again, indicating its close association with the act of eating. This term encompasses various types of meals, whether they are formal or informal, and is a way to describe the food itself or the occasion of eating.

The other words do not relate to meals or food in the same way. "Diminutive" refers to something that is small in size or stature. "Proselytize" means to convert someone from one belief or faith to another, typically in a religious context. "Infirmity" denotes a physical weakness or illness. None of these words pertain to food or meals, which is why "repast" is the accurate choice in this context.
