Usage and Grammar

Q. May I please ask if nouns can sometimes be used as verbs. For example, “His emotions nuance his words.” Thank you.

Q. It grates on my ear to listen to the BBC (particularly sports) newscasts talk about countries in the plural form, e.g., “England are preparing for next week’s match.” Can this be correct? I only began noticing it a couple of years ago, and I seem to recall that the practice even extends to cities or team names (Bayern Munich are out of the playoffs . . .). Your assistance would be much appreciated.

Q. Dear CMOS, I know you aren’t a grammar usage source, but for lack of knowing where to look, I wonder if you might know which word—“be” or “is”—would be correct here. “The senior management plan specifies that the lump sum rate in effect at termination (be/is) used to project interest to the regular retirement date.” I believe the correct word choice is “be,” but I’m not sure why. Can you offer any expertise? Thanks for your help!

Q. I work for a software company catering to law firms. In a law firm’s name you might use “et al.” if the firm name is long. What is the proper way of doing so?

Q. Could you please tell me the difference between toward and towards?

Q. What is the proper use of “would” or “could” in sentence structure? For example, would you please close the door? Or, could you please close the door?

Q. A number of educated friends tell me that “sans” is archaic and affected; they frown when I use it and instead encourage “without.” What do you think?
