„There is always the danger that the use of traditional grammatical terms with reference to a wide variety of languages may be taken to imply a secret belief in universal grammar. Every analysis of a particular ‘language’ must of necessity determine the values of the ad hoc categories to which traditional names are given. What is here being sketched is a general linguistic theory applicable to particular linguistic descriptions, not a theory of universals for general linguistic description.“
— John Rupert Firth English linguist 1890 - 1960
