Question

should there be a comma before the highlighted word? black widow will walk the dog, after she gets home today.

Explanation:

To determine if a comma should precede "after", we analyze the sentence structure. The main clause is "Black Widow will walk the dog" and the subordinate clause "after she gets home today" is an adverbial clause of time. When an adverbial clause of time follows the main clause, a comma is not typically used before the subordinating conjunction (here, "after"). So, there should not be a comma before "after".

Answer:

No, there should not be a comma before the highlighted word "after".
