        A number of researchers have studied conversations between speakers of English as a Lingua Franca and have noted a number of somewhat surprising characteristics, including:

        •  Use of an all-purpose tag question such as isn’t it? (They should arrive soon, isn’t it?)

        •  Increasing of redundancy by adding prepositions {We have to study about… and Can we discuss about…)

        •  Pluralisation of nouns which are considered uncountable in native-speaker English. (informations, staffs)

        The evidence suggests that non-native speakers are not conforming to a native English standard. Truly, they seem to get along perfectly well despite the fact that they miss things out and put things in which ‘they should not do’.
