Difference Between Intra and Inter


While it may sound confusing, the main difference between the two lies in the mere definition. Inter denotes something between two groups, objects, or persons. In contrast, intra helps indicate anything within the place or thing. 


You can only use the term intra to define something taking place between one group or place. It cannot involve more than one group.

On the other hand, you can use the prefix inter to denote two or more groups. It can be any activity between two separate groups, schools, institutions, organizations, places, etc.  

Use Cases

If something occurs within one organization, you will use the prefix intra for it. However, if two or more organizations are participating in it, the prefix inter would be the right choice. 

Intra involves only one thing or group, while inter can denote anything with more than one group or place. 


Although the two prefixes are quite commonly used, here are some of their most popular uses:

InterInteraction, internet, international, interview, interface, interfere, interest, interlope. 

IntraIntrapersonal, intranet, intransitive, intransigent, intraspecies, intramuscular, intratextual.
