English has already penetrated every society. Its penetration has also reached Albanian speaking societies, including Albania, Kosovo, and Macedonia. However, Albanians often use L1 rules when converting their thoughts into L2, especially in the context of adjectives. This is due to the lack of recognition of existing similarities and differences between English and Albanian adjectives. That is why we dedicated our book to a comparative study of adjectives so as to reveal the similarities and differences prevailing between English and Albanian. This book deals with the morphological and syntactical aspects of adjectives, and contains a mixed descriptive and comparative approach. It is illustrated with examples and can be easily followed. By learning adjectives' similarities and differences, the possibility of making mistakes while using them will be reduced in a great percentage. This book is of great importance for students, teachers, and linguists of both languages. It is designed to serve as a useful reference material for schools, universities, and relevant institutions when dealing with adjectives. In addition, it also gives a contribution to the field of Contrastive Analysis.
