1.1Discourse
.Discourse has been defined by different linguists ,and each one gives specific definition to it ,and we will go through all of them . In other words discourse is a buzzword and used in many different ways. The term discourse refers “both to what a text producer meant by a text and what a text means to the receiver” (Widdowson 2007: 7). As Widdowson claims, “people produce texts to get a message across, to express ideas and beliefs, to explain something, to get other people to do certain things or to think in a certain way” (Widdowson 2007: 6). According to the Verdonk’s definition discourse is “process of activation of a text by relating it to a context of use” (Verdonk 2002: 18). It follows that a successful analysis has to consider not only the text but its context as well. The terms text and context will be explained later.
As Potter and Wetherell say that Discourse and discourse analysis is a field in which it is perfectly possible to have two books [on the matter ] with no overlap in content at all (Potter & Wetherell , 987:6). However , discourse may mean everything (Grant et al .,1998; Kennoy et al ., 1997). Discourse is language in sequence beyond the sentence .(Tannen,1984).Other researchers such as (brown & Yule 1993) specify discourse as language in use . A discourse is a set of meanings through which a group of people communicate about a particular topic. Discourse can be defined in a narrow or a broad sense and a narrow definition of discourse might refer only to spoken or written language. However, discourse analysis more often draws on a broader definition to include the shared ways in which people make sense of things within a given culture or context, including both language and language-based practices (i.e. the ways in which things are accomplished). The term discourse was first used in modern linguistics by Zelling Herris in 1952 , but it can be traced back to
