What does Je tellement mean in English?

"Je tellement" is not a complete sentence in French. It's a fragment that translates to "I so" in English.

To understand the full meaning, you need the context of the entire sentence. For example:

* "Je tellement aime la musique." (I so love music.)

* "Je tellement veux voyager." (I so want to travel.)

* "Je tellement suis fatigué." (I am so tired.)
