The aim of the present coure in morphology is to acquaint the students with the structure of English words by defining  the minimal building blocks known as morphemes, specifying their phonological, semantic and distributional properties, and formalizing the principles governing the combination of morphemes into words. The word is shown to be an expansive category in English in that it can contain not only lexical categories, whether bound or free, but also phrasal categories up the the clause level. The properties of English words require that morphology and syntax should be integrated.
