comma before 'too' [adverb, end position]: on the choice, too.

[piedina]

Hi,

I tried to understand the "too"-rule: in other words, when should I put a comma before "too" and when not?

I am still not sure, if my sentence is correct (red):

"(I describe other factors, which determine the joint clearance) .... Finally the filler metal has a strong influence on the choice of the joint clearance, too."

What do you think?

Thanks!!

It is optional. You use the comma if you feel a pause is desired.

I like potato chips too!
I, too, like potato chips!

For the actual sentence you wrote, I would suggest also, and placing it differently. And you probably don't need both finally and also since both are words that help you transition from the previous sentence; using both seems like overkill. I took a stab at it. I'm not fully sure I understand your sentence.

The filler metal is also important for the choice of joint clearance.
