Definition of the word expand on

The phrase "expand on" comes from the English verb "expand," which means to spread out or expand, and the preposition "on," which indicates a relationship or connection with something. The origin of the word "expand" can be traced back to the Old French "espandre," which literally translates to "stretch out." This French verb is believed to have derived from the Latin "spandere," which also means "spread out." The original meaning of "expand" in Middle English was to gloat or spread out one's chest as a sign of pride or superiority. By the 14th century, however, the meaning expanded (pun intended!) to include the idea of making something larger or more spacious through the addition or extension of its parts. The phrase "expand on" emerged in the 19th century and gained popularity in the field of academic writing, where it was used to describe the process of developing an argument or idea by providing additional details, examples, or evidence. Today, "expand on" is widely used in both spoken and written English to indicate the need to provide further clarification, explanation, or elaboration. In summary, the origin of the word "expand on" can be traced back to the Old French word "espandre" and its Latin root "spandere," and its usage evolved over time to represent the idea of making something larger or more detailed through the addition or extension of its parts in various contexts, such as academic writing and informal communication.
