No two synonyms are exactly the same: they may have subtly different meanings or be used in different contexts. For instance, the words blunt, candid, forthright, frank, and outspoken are all synonyms of each other because they all have roughly the same meaning, but there are subtle differences. The ‘Choose the Right Word’ panels are devoted to explaining the differences in meaning between such groups of close synonyms. The distinctions are based on careful analysis of actual usage as recorded in the Oxford English Corpus (see Linguistic evidence). This analysis involved the most up-to-date computational techniques to sift large amounts of data, as well as traditional lexicographical analysis.
