《評論》Usage of "LESS"

Ha, what an arrogant creature is longing for my answer. Very well! Do you know that your so-called girl-singer example is WRONG? You applied the LESS wrongly. Your sentence shows your English usage ability is low! I don’t know why I should respond to your madness. Did you say that: coffee less sugar, please. = 咖啡不要糖。 (less as preposition)? Then you keep arguing like this: Coffee less sugar". The purpose of my sentence is to show that when used as a preposition, less does not mean a smaller quantity. Less means "to take away from". ========================================================= Look it up into your dictionary again, dude! (as you always do)(DON’T COPY IT AS YOUR OWN WORK OK! IT’S ILLEGAL!) Compare these sentences below, so you should find an answer. If you don’t, ask your English teachers for more help! Don’t spend your lifetime on this web to disguise as a hero. Garlic2010’s sentence: I like the songs of these girl-singer groups, Super Gear, As One, Super Girls, LESS their vocal part. (INCORRECT WORD CHOICE!!!) My sentence: She will stay in our house for a month LESS two days. (CORRECT USAGE of LESS) At last, let me ask you these questions to help your own clarification. Does coffee comes with sugar? Are coffee and sugar uncountable nouns? If so, how can you subtract them? Are you a mathematics nuts? I’m afraid so!
