Dear RonBee:
I review our former discussions on my manuscript today and learn more from your corrections. However, something still puzzles me. For example, the however in the following sentence, must we use a comma after the however? Why?
Thanks in advance!
First, we shut off the IR laser and struck the solid sample surface with one or a few laser pulses, and then as soon as possible, we opened the IR laser; however, no scattered light could be observed.
Yes, you need a comma after however there. The simplest explanation for that would be that in speech there would be a pause after however. The other explanation that comes to mind (and it isn't much of one) is that however functions like nevertheless, and nevertheless takes a comma after it. Perhaps something additional (and more useful) will occur to me.Originally Posted by wpqin

As 'however' connects two sentences, it has commas around it to separate it from the sentence it occurs in.
Wouldn't that make it a conjunction? I see using "however" at the beginning of a clause but not as a conjunction.As 'however' connects two sentences, it has commas around it to separate it from the sentence it occurs in.

Thank you, my teachers. I have gotten some about that.
So it's a conjunct and not a conjunction. (Thanks for the link.)
