What does the prefix "inter-" signify?

The prefix "inter-" signifies "between." It is derived from Latin, where it means to engage in action or to exist or occur in the space or time that separates two entities. This prefix is commonly used in various terms such as "international" (between nations), "interpersonal" (between people), and "intersect" (to cross between paths).

Understanding the meaning of prefixes like "inter-" can enhance comprehension of complex words and their relationships. In contrast, the other options represent different prefixes with their own distinct meanings, such as "in-" denoting "not" or "inside," and "extra-" pertaining to "outside." These distinctions are essential for accurately interpreting words and their usages in context.
