What does the prefix INTER- mean?

• A. Between
• B. Within
• C. Against
• D. Toward

Answer: (A)

Inter- means between or among, signaling a relationship that spans two or more parts or spaces. In medical terms this shows up when describing something that occurs between structures or across a boundary. For example, intercostal refers to something between the ribs, and intercellular communication happens between cells. This is different from intra-, which means inside or within; anti-, which means against; and the prefix that means toward, typically ad- (as in adduction), which describes movement toward a point or side.
