In EFL context, there is a considerable shift from single word lexical items to phraseology. Idioms constitute a core part in the phraseology block of the language. Idioms, in spite of their variety and cultural roots, are one of the most neglected areas in EFL perspective. Non-native learners of English as a foreign language do not feel motivated to use idiomatic resources of the language creatively. It is also a fact that pedagogy of idioms to EFL learners has been a challenging task for non-native teachers of the English language. The undertaken research is an effort to establish the utility of the entomological background of idioms in EFL class.
