insert

Insert refers to the act of putting something into another thing. As a verb, it means to place something inside or between something else, often with alignment or a fit. It can be transitive, as in "insert a key into a lock," or intransitive in phrases like "to insert oneself into a conversation."

As a noun, an insert is an item placed inside or attached to something else. In publishing, an insert is a separate sheet or advertisement inserted into a newspaper or magazine. In packaging, an insert is a leaflet or coupon enclosed with a product.

In computing, an insert operation adds an element at a specified position within a sequence. In SQL, the INSERT statement creates a new row in a table. In data structures, insertion may require shifting elements or adjusting links. In text editing, insert mode governs whether typed characters replace existing ones or are inserted.

In hardware and devices, an insert can refer to a removable component that is placed into a host device, such as a SIM card, SD card, or cartridge. In audio and video production, insert points are locations where external processors or effects are connected in line with the signal path.

Overall, the concept of insertion centers on adding, placing, or attaching something within or into another object or system.
