What does the prefix "trans-" mean?

The prefix "trans-" means "through" or "across." It is derived from Latin, where it conveys the idea of moving from one place to another or through something. This prefix is commonly used in various terms across different fields. For example, in the word "transport," it signifies carrying something from one location to another, while in "transmit," it refers to sending something across space or through a medium.

In contrast, the other options pertain to different meanings: "fast" does not connect to any connotation of movement or traversal. "Liver" and "vein" are anatomical terms and do not relate to the prefix "trans-" at all. Thus, recognizing "trans-" as a prefix indicating movement or passage is essential in understanding its application in various contexts.
