37. Who/Whom Use who when you are referring to the subject of a clause Use whom when you are referring to the object of a clause. *Remember: the subject of the sentence is the person doing something, and the object of the sentence is having something done to them. *If I step on Squiggly, then I am the subject and Squiggly is the object.

38. Who/Whom Quick Tip! Like whom, the pronoun him ends with m. When you're trying to decide whether to use who or whom, ask yourself if the answer to the question would be he or him. That's the trick: if you can answer the question being asked with him, then use whom, and it's easy to remember because they both end with m. For example, if you're trying to ask, "Who (or whom) do you love?" The answer would be "I love him." Him ends with an m, so you know to use whom. But if you are trying to ask, "Who (or whom) stepped on Squiggly?" the answer would be "He stepped on Squiggly." There's no m, so you know to use who.

47. Farther/Further The quick tip is to use “farther” for physical distance and “further” for metaphorical, or figurative, distance.

52. A tip! Think of the grocery store express lane. Most of the signs for these lanes read, “10 items or less,” and that's just wrong. The signs should read, “10 items or fewer,” because items are individual, countable things!

61. Which/That Use that before a restrictive clause Use which before everything else What is a restrictive clause?--Part of a sentence that you can't get rid of because it specifically restricts some other part of the sentence. Ex: "Cars that have hybrid technology get great gas mileage." Are all cars hybrids? No. Therefore it is restrictive…it is a detail that MUST be included. The science fair, which lasted all day, ended with an awards ceremony. Which lasted all day is not crucial to the sentence or its meaning.

62. Dear Abby… Dear Abby is the name of the advice column founded in 1956 Still syndicated today and appears in newspapers

63. Dear Abby Example DEAR ABBY: I am 16 but will be 17 in a few months. I have known my boyfriend, "John," for two years. He is my first boyfriend. After four months of dating, John has asked me to marry him, and I said yes. He had been hinting about an engagement, and I didn't have the heart to say otherwise. John is very dear to me, but I keep hearing people say, "Keep your options open." I told John that I am young (he's 18), and I want to take it slowly, but he says if I break up with him to date other guys, he will never date me again. Abby, I want to make sure John is the person I want to spend the rest of my life with. Sometimes I wish I hadn't started dating him because I feel too young to be engaged or married. I love John dearly. I don't want to break his heart or mine. I am also scared I might mess up this relationship. What should I do to make myself believe that I have found my true love? --- STUCK IN OKLAHOMA

64. Dear Abby example response.. DEAR STUCK: You should have been absolutely honest with John from the beginning. When you have found your own true love, you won't have to "make yourself" believe it. You will KNOW it. John is pressuring you because he is afraid if you start dating others he won't measure up. For both your sakes, tell him that you are not ready to make the kind of commitment he is demanding. He may not like hearing it, but it is the truth. You won't break his heart, and once you have done it, you will feel a sense of relief.
