What does the prefix "Inter-" signify?

The prefix "Inter-" signifies "between" or "among" in various contexts. It is commonly used in medical and scientific terminology to indicate relationships or interactions that occur between two or more entities. For example, in terms like "intercellular," it refers to something happening between cells. This prefix helps to convey the idea of connectivity or interaction, which is essential in fields such as biology and medicine where the relationships between different systems or components are crucial for understanding functions and processes. The other options do not accurately reflect the meaning of "Inter-," as they refer to different spatial or positional relationships that do not relate to the concept of being between.
