【正确答案】Synonymy is the technical name for the sameness relation. English is said to be rich in synonyms. For example, buy and purchase, world and universe, brotherly and fraternal. But total synonymy is rare. The so called synonyms are all context-dependent. They all differ one way to another. For example, they may differ in style. In the context, “little Tom ___a toy bear”, buy is more appropriate than purchase. They may also differ in connotations. That is why people jokingly say “I’m thirsty.

The British live in flats and take the underground or tube to work while the American live in apartment and take the subway.
