I see it both ways with a comma before a sentence-ending 'too' and a comma on each side of 'too' when it's the second word in a sentence. Are these commas really needed? Would you personally use them? I think we could leave these sentences as is without the commas. Do you concur?
He too makes a few unforced errors, and we're at deuce. (Comma needed before and after 'too'?)
She too admired his looks and his courtliness. (Comma needed before and after 'too'?)
She admired his looks and his courtliness too. (Comma before 'too'?)
He wanted to go too but decided not to. (Comma before and after 'too'?)
He wanted to go too, but he decided not to.(Comma before and after 'too'?)
He too puts commas around 'too'. (Comma before and after the first 'too'?)
Headline: Obama Says He Too Is a Poverty Fighter In D.C., He Offers Contrast With Edwards (Comma before and after 'too'?)
Using Commas to Prevent Misunderstanding Sometimes you must use a comma to make the reader pause in the appropriate place in the sentence in order to prevent misreading. Becoming a good writer means developing an awareness of how your sentences will sound to the reader. Reading your work aloud, to yourself or to a friend, is a good way to identify the places in the sentence where pauses--or commas--are needed.
