I have a question concerning the term "round" in my sentence:
1.Give me a round dozen and Iíll pay in cash.
Here 'round' means a neat, convenient, even number. A dozen is not normally considered round. Perhaps he's only paying for 10, and thinks this is a good ploy to get two more for the same price.
10 is a round number; 9.91 isn't. In fact you can "round up" 9.91 to 10 if the discrepancy isn't important. You 'round down' 5.12 to 5.
Eight is a round number of guests for a dinner party, if your table seats eight.
2.He invited us round for drinks.
This is short for 'around'. I'd use 'around' in writing. You go around to his place. This could be an adverb here [?], though it's a preposition in "I'm going around the corner".
3.This reminds me of 'a round of drinks'
Here, everyone begins drinking at the same time, and everybody gets a new drink at the same time. Each batch of new drinks is a 'round'. Sometimes person A will pay for the first round, B will pay for the second. (You'll probably see the disadvantages of this system.)
As for the first sentence, I want to know if I say "round dozen", it means 12, but what if I merely say "dozen"? A dozen is 12.
As for the second sentence, what does the "Round" mean?
Thanks a lot
