ABSTRACT
Morphology is concerned with word structure and word formation. On the one hand, it deals with inectional morphology, i.e. the creation of word forms, such as book (singular) versus book+s (plural). Books is not a new word, and it would not get its own entry in the dictionary. Rather, it is just a new form of the word (or lexeme) book. On the other hand, morphology also looks at how lexemes are built through processes such as axation (e.g. possible and im+possible), compounding (e.g. wall + paper = wallpaper), clipping (refrigerator > fridge) and so on. Both of these domains of morphology are aected by linguistic change.
