This is the kind of tedious nonsense up with which I will not put! Which grammar rule was Winston Churchill supposed to have objected to? Don't start a sentence with but Avoid splitting an infinitive Never end a sentence with a preposition Sometimes you should use "that" and sometimes "which." Which sentence here is wrong? The car which ran me over was speeding The car that ran me over was speeding The car, which was speeding, ran me over Consider this sentence: "Do you mind my asking you?" Which of the following does it include? Modal Gerund Imperative Which of the following is not correct? I was sitting in the chair I sat in the chair I was sat in the chair The Queen arrived at the castle with the King by her side, in a dress adorned with hand-sewn embroidered dragons. What kind of mistake is this? Fallen subjunctive Misplaced modifier Dangling participle It's the third one. "Who's" is short for "who is," whereas "whose" is used to describe items that belong to someone. The garden belongs to the neighbour (singular) so needs an apostrophe before the "s." It's might. The use of may or might varies according to context. In this case, because the victory did not result in a turning point, one chooses the more hypothetical might. May would be correct only if the turning point had happened. He's male. The absence of a comma before "who doesn't," implies that there are other brothers. A comma after "my brother" would mean that there was only one brother. It's coffees. For "countable" things use fewer. For things that are not "countable" - such as water in the river - use less. It's landing a plane. Here it links two independent clauses. You do not use it before a conjunction such as "and" or "but." A colon or dash would work better in the last sentence. It's the preposition. The story is apocryphal. It is likely that the comment came from a memorandum written by one of Churchill's civil servants. It's the first one. "That" defines something, whereas "which" adds new information in a separate clause, often needing commas. It's a gerund. A gerund is a noun made from a verb by adding "-ing." It's "was sat." To use "was" requires the participle "sitting" after it. It's misplaced modifier. This is a clause placed so awkwardly as to create ambiguity or misunderstanding. A dangling participle is a type of misplaced modifier involving a participle. Fallen subjunctive does not exist. 0 - 3: Colon confusenik 4 - 7: Promising pedant 8 - 10: Grammar guru
