Transition words are used to connect ideas and create smooth transitions between sentences and paragraphs. "You" is a pronoun, specifically a personal pronoun, and it refers to the person being addressed.
Here are some examples of transition words:
* Addition: and, also, in addition, furthermore
* Contrast: but, however, on the other hand, nevertheless
* Cause and effect: because, therefore, as a result, consequently
* Time: first, then, next, finally
