External vs. Outside: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on November 7, 2023
External means relating to the outside or outer part. Outside means not inside; externally located.

Key Differences

External is a term that's often used in various contexts, from anatomy to buildings, indicating something on or related to the outer part. Outside is a word that's used to specify a location that's not within the confines of an area, such as a building or room. It's more about location than position or relation.
In the medical or biological context, external refers to something situated on or near the surface of the body. For instance, external injuries. Outside in such contexts isn't commonly used; it's more about spatial positioning in everyday scenarios, like being outside a house.
When discussing objects or aspects not intrinsic to the main subject, external is the go-to word. For example, external factors affecting a project. Outside, however, is better suited to denote physical location or placement, as in someone waiting outside a door.
In technology or devices, external components are those attached but not integrated into the main system, like external hard drives. Outside, in contrast, could refer to being in the open air or out of a particular space, such as outside an office.
External can also describe influences or resources coming from outside an organization or system. For instance, external funding. Outside might be used more colloquially or physically, indicating a place that's not within an enclosed area.
