Generally, you *do* put a comma after "apparently" if it introduces a clause:
* Example: "Apparently, the meeting has been postponed."
In this case, "apparently" is acting like an introductory phrase, similar to "however" or "therefore," and should be followed by a comma.
However, if "apparently" is used as an adverb modifying a single word or phrase, you *don't* need a comma:
* Example: "He was apparently very tired."
Here, "apparently" is directly modifying "tired" and doesn't require a comma.
Here's a quick way to check:
* If you can replace "apparently" with "it seems" and the sentence still makes sense, use a comma.
* If you can't replace "apparently" with "it seems" without changing the meaning, don't use a comma.
Ultimately, the best way to determine if a comma is needed is to consider the sentence structure and how "apparently" is being used.
