语源
  1. Middle English: from Old French reisun (noun), raisoner (verb), from a variant of Latin ratio(n-), from the verb reri 'consider'
用法
  1. 1 The construction the reason why … has been objected to on the grounds that the subordinate clause should express a statement, using a that-clause, not imply a question with a why-clausethe reason (that) I decided not to phone rather than the reason why I decided not to phone
  2. 2 An objection is also made to the construction the reason … is because, as in the reason I didn't phone is because my mother has been ill. The objection is made on the grounds that either ‘because ’or ‘the reason ’is redundant; it is better to use the word that instead the reason I didn't phone is that …or rephrase altogetherI didn't phone because …Nevertheless, both the above usages are well established (nearly 20 per cent of relevant citations in the Oxford Reading Programme are for the construction the reason … is because, for example) and, though more elegant phrasing can no doubt be found, they are generally accepted in standard English
