Think of it like this:
* Inter-disciplinary: This refers to work that crosses between different disciplines, like combining history and psychology.
* Intra-disciplinary: This refers to work that stays within a single discipline, like a history paper focusing solely on the history of a particular event.
Here are some examples of intra-disciplinary work:
* A biologist studying the reproductive cycle of a specific species.
* A chemist researching the properties of a new compound.
* A sociologist examining the social dynamics of a particular community.
In essence, intra-disciplinary work focuses on deepening knowledge and understanding within a specific field of study.
