I, of course, think that using correct grammar is important.
I, however, think that using correct grammar is important.
I, therefore, think that using correct grammar is important.

Are the commas in the above sentences optional? If so, what difference do they make?

Personally, I think I'd always use the commas in the first two, but I don't think I'd ever use commas in the third one.

I'll be interested in seeing what others think.

Yankee, Verade

My reasoning was that "I think that using correct grammar is important." makes perfect sense, so anything between "I" and "think" should (or could) be enclosed by the commas. It seems to be the case with "however" and "of course", but why are you treating "therefore" differently?

I would put commas between therefore because  that gives a speaker a pause.

The lack of a pause is precisely why I would not use a comma in the third sentence.  I would not pause there -- probably because that is not an unusual  location in that sentence for the word 'therefore'.

However, the words 'of course' and 'however' definitely interrupt the sentence when inserted in the middle of "I think", and I would pause before and after if I inserted those words in that particular place when speaking.

Yankee, thanks for your help, but I am still not sure what is going on here.

Should the commas be left out in the following two sentences?

I consequently think that using correct grammar is important.
I thus think that using correct grammar is important.

"consequently" and "thus" are synonyms of "therefore", but I don't know whether they should be treated the same grammar-wise.

Hi Akavall

I would not use commas with consequently in that position.  I doubt that I would insert the word 'thus' into the middle of "I think", but if I did, I would not use commas there either. 

To me, the only possible reason to use commas with 'however' (in your sentence) would be if someone else had just given an opinion different from mine, and I then wanted to stress the word 'I' -- i.e. to place extra emphasis on the fact that there is a difference between what I think and what they think.

So if I said:

Authors should not spend a lot of money on editing their books. I however think that using correct grammar is important.

I am not disagreeing with anybody; I am just changing the course of my initial idea. No commas?

I think I got the "therefore" part.

Thanks a lot for helping me with this Smile [:)].
