insert
This term conveys a sense of precise placement, often involving a tight fit or a specific designated space. When used as a verb, it suggests a deliberate action of putting one object into another, whether physically, like a key into a lock, or digitally, like a line of code into a script. As a noun, the word refers to supplementary material that is not part of the main body of a work but is tucked inside. This creates a distinction between the primary content and the additive element, such as a promotional flyer inside a newspaper.
