Language is a means of communication thoughts
and feelings, though not the only means. Cries, signs,
gestures, pictorial representations, etc., also serve as a
means. Man alone uses language for communication
[30]. The term applied linguistics seems to have
originated inthe United States in the 1940’s. The
creation of applied linguistics as a discipline represents
an effort to find practical applications for modern
scientific linguistics [8]. Applied linguistics is often
said to be concerned with solving or at least
ameliorating social problems involving language.
Schmitt and Celce-Murcia [31] argued that “Applied
Linguistics is using what we know about (a)
language, (b) how it is learned and (c) how it is used, in
order to achieve some purpose or solve some problems
in the real world” [32]. In recent years, the role of applied
linguistics in English language teaching (ELT) has been
considerable in designating English academic courses at
universities, teacher training institutions, English
materials and providing the programmes for English for
specific or general purposes for English learners around
world. In addition, the relation between Linguistics and
language teaching is necessary, from of this point of
view, Taylor [33] pointed out that “some specific
linguistics knowledge is required by the language
teacher-for assessment, for choosing learning activities,
for course planning and design.” Halliday [34] mentioned
that the principle contribution of linguistics to language
teaching is to provide a revealing description of the
language being taught.
