Synonym discussion

Sense: noun/3

For noun sense 3, 'opening' is useful when you mean the first part of something that people can notice and react to: the opening of a film, a speech, or a match. 'Beginning' is the broad everyday word and works almost anywhere. 'Start' is also common, but it often points more to the moment something begins than to the early section that follows. 'Outset' is formal and appears most often in phrases like 'at the outset'. 'Introduction' is narrower: it is the part that prepares you for the main body. You can say 'The film's opening was exciting', 'The meeting started late', and 'At the outset, the chair explained the rules.'

Etymology

Old EnglishEnglish

The word 'opening' was formed in English from the verb and adjective 'open' plus the ending '-ing'. Old English 'open' meant 'not shut'. At first, 'opening' named the action of making something open. Later it also came to mean the gap created, the first part of something, and by extension events or performances that happen first.
