Here are some examples:
With a time expression:
* "Before John left, he made sure the door was locked."
* "Before Christmas, we usually go to see the lights."
With a comparative phrase:
* "Before Shakespeare, there were other great playwrights."
* "Before Einstein, scientists had a different understanding of gravity."
With a prepositional phrase:
* "He lived in the house before Mary."
* "The events that happened before World War II are important to understand the current situation."
With a phrase indicating order or sequence:
* "Before John, it was Sarah's turn."
Important Note:
While grammatically correct, using "before" directly before a proper noun can sound awkward or overly formal in casual conversation. It's more natural to use phrases like:
* "Before John left..."
* "Before Christmas..."
* "Before Shakespeare's time..."
Ultimately, the best way to use "before" with a proper noun depends on the context and the intended meaning.
