Vocab Builder: Comparing Intra- and Inter-

We continue our look at prefixes with a pair that people often confuse: intra- and inter-. Intra-, meaning within or inside, comes from the Latin intra, which also means within. Interestingly, the Online Etymology Dictionary notes that the prefix intra- was not often used in Latin. Inter- is also Latin, meaning between or among, as well as reciprocally. The Latin term is believed to descend from the Proto-Indo-European (PIE) *enter, also meaning between or among. An intranet, then, is a network only for those within a certain group, such as a company, while the Internet is a network open to anyone. Let’s look at some more intra- and inter- words.

  • intramural, adjective: occurring within one community, such as sports within a college.

Republican prospects rest on the savvy and intramural statesmanship of a trio of leaders who were hunkered down last week in an otherwise deserted Capitol: Gingrich in the House, Bob Dole and Phil Gramm in the Senate. —Newsweek

  • intrapersonal, adjective: occurring within one’s self.

The psychological variant emphasizes the intrapersonal origins of poverty: emotional problems (for example, depression) or lack of interpersonal abilities (Alcock, 1997). —Social Work
