Comma -
The main rule for the use of commas in English is: Keep your sentences clear. Too many commas might be distracting; too few might make the text difficult to read and understand.Always check your texts on readability. This requires some practice, however, as first you must know which commas are necessary and which are optional.
The following contains explanations on English comma rules.
Commas with Adverbs
Use a comma after certain adverbs: however, in fact, therefore, nevertheless, moreover, furthermore, still, instead, too (meaning ‘also’).
Example: Therefore, he didn’t say a word.
If these adverbs appear in the middle of a sentence, they are enclosed in commas.
Example: The thief, however, was very clever.The comma is optional for the following adverbs: then, so, yet.
Example:
So, she entered the house.
So she entered the house.
