Sparky: Where is that video we made the other day?

Mr.Maru: It’s on the computer.

Sparky: I can’t find it, where did you put it?

Mr.Maru: It’s on the intranet hard drive.

Sparky: Um, is that on Google?

Mr.Maru: No, the intranet.

Sparky: I’m on the intranet, what website do I go to?

Mr.Maru: No, I mean the net inside the house, not between computers. That’s the internet.

Sparky: Oh, so, could you just show me?


What is the difference between intra- and inter-. These prefixes sound very similar, but they are very different. Let’s go over some examples and how to use these prefixes.

intra-differenceHow to use intra-

The prefix ‘intra’ means inside or within. We can see it in many words like intranet, a network inside a house or office building. Let’s look at some quick examples:

I played on an intramural volleyball team when I was in junior high school. (I played on a team that only played within my junior high school not other schools.)
I did an intra-company transfer to the sales department in Chicago. (I stayed within the company, but I transferred to the Chicago office.)

The prefix ‘intra’ is used with a variety of medical words. For example,

intracranial – within the skull
intravenous – inside the vein (the tube in the body that blood travels through)

The prefix ‘intro’ means almost the same thing ‘within or inwardly.’ It is used in a lot of words borrowed from latin like introspection (look inside yourself) and introduce (lead someone inside or personal side)

inter-differenceHow to use inter-

The prefix ‘inter’ means between or among. We can see it in many words like internet, a network of computers across the world. Let’s look at some quick examples:

The Olympics are an international sporting event. (The sports games are played between nations.)
This class is for intermediate students. (This class is for students in among the middle level.)
