* "Also" is an adverb: It modifies a verb, adjective, or another adverb. It doesn't function as a conjunction that connects independent clauses.
* It's usually part of a phrase: "Also" often appears within a phrase, like "also important," "also available," etc.
Examples:
* Correct: He is also a talented musician.
* Correct: The cake was delicious, and also very moist.
* Incorrect: He is, also, a talented musician.
Exceptions:
* When "also" introduces a contrasting element: You might use a comma after "also" if it introduces a contrasting element, similar to how you'd use a comma with "however."
* Example: I enjoy reading, but I also enjoy listening to music.
* For clarity: If your sentence is complex and you feel the comma would help with clarity, you can use it. This is more of a style choice than a strict rule.
In most cases, "also" doesn't require a comma after it.
