Based on (as a source/material)
Category: Relation & Perspective
This grammar pattern is used to indicate that something was created or made based on a particular source or material. The focus is on the source rather than the authority or rules. It is often used in informal or creative contexts, such as writing a story or making a product. The pattern can be used to describe the process of creating something new, and it emphasizes the role of the source material in shaping the final product.
