Summary: Prefixes are key morphemes in English vocabulary. The prefix *trans-* and its variant *tra-*, which mean "across," appear in many English vocabulary words, for example: [*trans*]mit, [*trans*]form, and [*tra*]jectory. Consider the word [*trans*]lation, which is the carrying "across" from one language into another.
