The prefix "trans" is derived from Latin and is used commonly throughout the English language. There are many examples that can help determine the meaning of this prefix. Consider these few examples:
TransAtlantic flight --> A flight across the Atlantic ocean
Account Transfer --> A movement of an item across acounts
Translate --> express a word or phrase across languages
Note, in all three of these examples, the prefix "Trans" is used and we can understand that the meaning here is clearly Across.
