3、,即自由词根)and bound morphemes(粘着词素),5.1 what is morphology,Morphology studies the internal structures(内部结构)of words and word formation rules.It divided into two fields:inflectional morphology(屈折词法)and derivational/lexical morphology(派生词法).It studies the different categories of morphemes(bound,free,deri
