A reader asks about the differences between summary, review, and overview.
These three words are often used interchangeably, but they have slightly different connotations.
Summary is the broadest of the three. It refers to a short restatement of the main points of an argument, paper, lecture, etc. and especially a restatement used for better understanding, easier remembering, or showing how points relate to each other. It tends to be used most in academic contexts, but is also used quite a bit in magazines and newspapers.
Overview also refers to a restatement of the main points of something but has a more general connotation than summary. It tends to be used in academic contexts more than summary and has less general use in newspapers and magazines than summary does. But it is not formal: it also appears in spoken English more often than summary does.
Review is the narrowest of the three words and has several meanings. The first (and one of the most common) meanings of review is "a report giving someone's opinion about someone or something." This is used in both informal contexts ("movie reviews") and formal contexts ("This policy is under review."). This sense of review is also used in the name of magazines and academic journals that are full of these sorts of opinions ("Law Review", "The Annual Review of Biology").
The second use of review refers to a class, lecture, book, etc. that is meant to give you a very broad introduction to a subject ("a review of 19th century literature"). This use appears primarily in academic and formal contexts.
The third use of review is only found in American English and refers to studying information you have already studied before ("Do a review of Chapter 7 for the test."). This is the equivalent of the British word revision and it appears in informal and classroom contexts.
