　　Compliment/Complement -

　　Compliment with an 'i' means to say somethingnice, while complement with an 'e' means to matchwell with. "I like the cake" is a compliment. "Ibrought a pie" would be a complement. You canremember because it is I who gives compliments.

　　Discreet/Discrete -

　　To be discreet is to be secretive or careful (i.e. thieves are discreet when they steal. Tobe discrete means to be separated (i.e. two different piles of objects are discrete piles). Always look to see if there's a 't' to separate the two 'e's.

　　Who/Whom -

　　If you want to figure out which one is correct, rephrase the sentence as a question andthen answer it. For example, to know the correct use in "Mr. Porter called the author who/whomhe met in Portland", change it to "who did he meet in Portland?" and then answer the question. If the answer would be "he", use who; if the answer would be "him", use whom. Mr. Porter met'him' in Portland, so it should be "Mr. Porter called the author whom he met in Portland." Noticethat both 'him' and 'whom' end with 'm'.

　　Less/Fewer and Amount/Number -

　　Every sign in the grocery store you see that says, "10 items or less" is grammaticallyincorrect. It should read "10 items or fewer." Use the word 'fewer' with things you can count, and use the word 'less' with items you cannot. For example, there is less sand at this beach, sothere are fewer people here. You can't count 'sand', but you can count people. The same rule istrue for amount and number. The small amount of soda in your glass means you should have asmaller number of ice cubes. We can't count 'soda', but we can count ice cubes.

　　Affect/Effect -

　　In most cases, 'affect' will be a verb, and 'effect' will be a noun. If the word is preceded byan article (a or the), a preposition (into, for, etc.), or an adjective, the correct choice will be'effect'. Note that 'effect' can also be a verb if it is being used in the sense that somethingbrought something else into existence. "I affected the melon's price" means that I changed it. "I effected the melon's price" means that I created it.

　　Precede/Proceed -

　　To precede means to come before, while to proceed means to continue. You canremember this because 'e' comes before 'o' in the alphabet.

　　Bi-/Semi- -

　　The difference between biannual and semiannual is that bi- means every two years, andsemi- means twice a year. Semi- has more letters than bi-, so it occurs more frequently.

　　Councilor/Counselor -

　　A councilor is a member of a council, while a counselor is one who gives advice. In someways, you can consider a counselor to be one who sells their advice.

　　Hanged/Hung -

　　Pictures are hung and people are hanged. It is incorrect to say that, "the outlaw was hungat noon." He was hanged at noon.

　　Elicit/Illicit -

　　Detectives try to elicit information from witnesses (it's a verb), while things that arenaughty or illegal are illicit (it's an adjective). You can remember because things that areillegal are illicit.

　　Imply/Infer -

　　If you are implying something, you are giving information. If you are inferring something, you are interpreting information. For example, by creating this list of common errors tested onthe SAT, I am implying that you should study grammar, and you can infer that your score willincrease if you do.
