Contrastive analysis is concerned with the study of a pair of languages with the aim of discovering their structural similarities and differences. Contrastive Analysis is a method that was widely used in the 1960s and early 1970s to explain why some features of a target language were more difficult to learn than others. (Mozlan, 2015)
