The word "item" refers to an individual thing or object, especially in the context of a list or a collection of things. It can represent any single piece within a larger group. In conversations or activities, an "item" may also denote a topic, question, or point of discussion.
The word "item" comes from the Latin word "items," which means "in this way" or "also." It entered Middle English in the 14th century, retaining the sense of a single entity or point in a list.
