The prefix inter- denotes which relationship?

The prefix inter- denotes which relationship?

• A. Across
• B. Between
• C. Around
• D. Within

Answer: (B)

Inter- denotes a relationship between two or more distinct entities, signaling interaction or connection across boundaries rather than inside a single item. In animal behavior, this shows up in terms like interspecific interactions, which occur between different species, or intercellular signaling, which happens between cells. It does not mean within something—that would be intra-—nor around something (peri- or circum-), nor is it just a directional sense like across in some contexts. So the best understanding is that inter- means between.
