Over the past few years linguistics, and in particular lexicography, has paid much attention to the way in which words habitually group together in clusters that are not considered idioms but are yet felt to be frequent units of language comprising more than one word.Despite this attention , the concept of "collocation" is still somewhat vague and needs a clearer demarcation. Collocations appear to be a wide phenomenon in English-expressions such as highly qualified, a central feature, and receive severe criticism abound in the language and their importance for teaching has been increasingly recognized. However, it seems that collocations have not yet been generally integrated into teaching material, and, as a consequence, not been given serious consideration in the English classroom (Hodne : 2009) 1.1. What is Word-Collocation? Defining collocation is a challenge as the term of collocation has been a common concern among linguists, lexicographers and language teachers, however, the basic and general views regarding collocation will be mentioned in this section. The British linguist Firth is often quoted as one of the first who dealt with collocations. Inan article on modes of meaning published in 1951, Firth introduced his often-quoted definition of collocation as "the company words keep". He maintains that "meaning by collocation is an abstraction at the syntagmatic level and is not directly concerned with the conceptual or idea approach to the meaning of words". He gives the example of the word night where one of its meanings involves its collocability with dark.Palmer (1976) avers that Firth argued that "you shall know a word by the company it keeps", and he gave the example of the company of the English word ass, which occurred in a limited set of contexts and in the company of limited set of adjectives silly, obstinate, stupid, and awful. Leech (1974:20) discusses what he calls "collocative meaning" which "consists of the associations a word acquires on account of the meaning of words which tend to occur in its environment". This definition is almost a replica of Firth's definition and instead of ass, Leech gives the examples of pretty and handsome and the collocates of each. The words pretty and handsome share the common
