How is the comma "visible"?
The word "apparently" is distinguished by commas if, in the meaning of the sentence, it acts as an introductory word. In this case, the word "apparently" refers to the group of introductory words that express a certain proportion of the probability of what is happening. That is, if the meaning of "apparently" in a sentence can be equated to the meaning of the words "probably", "most likely", "should be", then it is marked with commas no matter where it is in the sentence: at the beginning, in the middle or in the end.
- "Apparently, today he decided not to go";
- "Today, he apparently changed his mind";
- "Today, he changed his mind, apparently."
When “apparently” is an adverb in a sentence, it is not given a comma. The adverb within the meaning can be equated with the meaning “clearly”, “obviously”: “Papa was apparently in the spirit” (A. Fet). Such a value is characteristic of literary speech and in modern speech almost never occurs.
