Regarding the first posture, some linguists claim that the variation in ELF is totally devoid of patterns and is therefore not to be studied. Most importantly, proponents of this view reject the idea that new knowledge about how English is used as a lingua franca can make a useful contribution to the goals and methods of teaching English. With regard to criticism of the elf and the formation of varieties, some argue that elf research has inherited the legacies of traditional linguistics, which contain certain obstacles to examining the use of language in the context. For example, there are allegations that variationist speeches have entered some ELF accounts, which place too much emphasis on recording forms of language and digital authentication, rather than taking into account all the factors and contextual variations that represent communication practices in the 11 parameters.    This leads to linear links between intent, behaviour, culture, etc. and English uses that may be false lines of corrolation. It also allows the focus to be on what is different and not on what exists, which moves from a descriptive agenda to a pragmatic (and probably problematic) agenda. Such criticisms are generally cooperative and complementary to the ELF field of investigation and are not as incomparably confrontational as those that adopt the previous or subsequent attitude. The way English is used as lingua franca depends heavily on the specific use situation. In general, elves interactions focus on function, not form.
 In other words, communicative efficiency (i.e. message transmission) is more important than correction.  As a result, ELF interactions are very often hybrid.  Speakers take into account each other`s cultural context and can also use code switching to other languages they know.  The following characteristics of ELF lexicography have been identified on the basis of the Vienna-Oxford International English Corpus (VOICE) :  Criticism of ELF generally appears in three camps: [citation required] Those who argue that the language studied is made up of learning errors and not genuine variations; those who argue that ELF scholars perpetuate the idea that ELF is a variety of English re-edified; and those who feel that it maintains conceptions of neutrality in the face of global supremacy through languages and discourses.
