From a website called LitReactor:
1. Who and Whom
This one opens a big can of worms. “Who” is a subjective — or nominative — pronoun, along with "he," "she," "it," "we," and "they." It’s used when the pronoun acts as the subject of a clause. “Whom” is an objective pronoun, along with "him," "her," "it", "us," and "them." It’s used when the pronoun acts as the object of a clause. Using “who” or “whom” depends on whether you’re referring to the subject or object of a sentence. When in doubt, substitute “who” with the subjective pronouns “he” or “she,” e.g., Who loves you? cf., He loves me. Similarly, you can also substitute “whom” with the objective pronouns “him” or “her.” e.g., I consulted an attorney whom I met in New York. cf., I consulted him.
2. Which and That
This is one of the most common mistakes out there, and understandably so. “That” is a restrictive pronoun. It’s vital to the noun to which it’s referring. e.g., I don’t trust fruits and vegetables that aren’t organic. Here, I’m referring to all non-organic fruits or vegetables. In other words, I only trust fruits and vegetables that are organic. “Which” introduces a relative clause. It allows qualifiers that may not be essential. e.g., I recommend you eat only organic fruits and vegetables, which are available in area grocery stores. In this case, you don’t have to go to a specific grocery store to obtain organic fruits and vegetables. “Which” qualifies, “that” restricts. “Which” is more ambiguous however, and by virtue of its meaning is flexible enough to be used in many restrictive clauses. e.g., The house, which is burning, is mine. e.g., The house that is burning is mine.
3. Lay and Lie
This is the crown jewel of all grammatical errors. “Lay” is a transitive verb. It requires a direct subject and one or more objects. Its present tense is “lay” (e.g., I lay the pencil on the table) and its past tense is “laid” (e.g., Yesterday I laid the pencil on the table). “Lie” is an intransitive verb. It needs no object. Its present tense is “lie” (e.g., The Andes mountains lie between Chile and Argentina) and its past tense is “lay” (e.g., The man lay waiting for an ambulance). The most common mistake occurs when the writer uses the past tense of the transitive “lay” (e.g., I laid on the bed) when he/she actually means the intransitive past tense of “lie" (e.g., I lay on the bed).
Contrary to common misuse, “moot” doesn’t imply something is superfluous. It means a subject is disputable or open to discussion. e.g., The idea that commercial zoning should be allowed in the residential neighborhood was a moot point for the council.
5. Continual and Continuous
They’re similar, but there’s a difference. “Continual” means something that's always occurring, with obvious lapses in time. “Continuous” means something continues without any stops or gaps in between. e.g., The continual music next door made it the worst night of studying ever. e.g., Her continuous talking prevented him from concentrating.
6. Envy and Jealousy
The word “envy” implies a longing for someone else’s good fortunes. “Jealousy” is far more nefarious. It’s a fear of rivalry, often present in sexual situations. “Envy” is when you covet your friend’s good looks. “Jealousy” is what happens when your significant other swoons over your good-looking friend.
“Nor” expresses a negative condition. It literally means "and not." You’re obligated to use the “nor” form if your sentence expresses a negative and follows it with another negative condition. “Neither the men nor the women were drunk” is a correct sentence because “nor” expresses that the women held the same negative condition as the men. The old rule is that “nor” typically follows “neither,” and “or” follows “either.” However, if neither “either” nor “neither” is used in a sentence, you should use “nor” to express a second negative, as long as the second negative is a verb. If the second negative is a noun, adjective, or adverb, you would use “or,” because the initial negative transfers to all conditions. e.g., He won’t eat broccoli or asparagus. The negative condition expressing the first noun (broccoli) is also used for the second (asparagus).
8. May and Might
“May” implies a possibility. “Might” implies far more uncertainty. “You may get drunk if you have two shots in ten minutes” implies a real possibility of drunkenness. “You might get a ticket if you operate a tug boat while drunk” implies a possibility that is far more remote. Someone who says “I may have more wine” could mean he/she doesn't want more wine right now, or that he/she “might” not want any at all. Given the speaker’s indecision on the matter, “might” would be correct.
9. Whether and If
Many writers seem to assume that “whether” is interchangeable with “if." It isn’t. “Whether” expresses a condition where there are two or more alternatives. “If” expresses a condition where there are no alternatives. e.g., I don’t know whether I’ll get drunk tonight. e.g., I can get drunk tonight if I have money for booze.
10. Fewer and Less
“Less” is reserved for hypothetical quantities. “Few” and “fewer” are for things you can quantify. e.g., The firm has fewer than ten employees. e.g., The firm is less successful now that we have only ten employees.
