I explained some issues about Korean adnominals(listed-words of ‘wulimalsaym’) on the perspective of word-formation. By cross-classifying Korean adnominals on two criteria(e.g. formal criterion, semantic/functional criterion), I could get conclusions as follows. First, based on the semantic/functional criterion, Korean adnominals can be classified into grammatical adnominals(e.g. deictic adnominals, interrogative/infinitive adnominals, modal adnominals) and lexical adnominals(e.g. state/property adnominals, numeral adnominals, modal adnominals). Second, based on the formal criterion, Korean adnominals can be classified into simple adnominals(e.g. root adnominals, base-modificated adnominals, partial-reduplicated adnominals) and complex adnominals(e.g. compound adnominals, derivative adnominals, full-reduplicated adnominals, ending-combined adnominals, cosa-combined adnominals). Third, most of grammatical adnominals are simple deictic adnominals, and most of lexical adnominals are simple state/property adnominals. Fourth, some adnominals can be classified into two or more categories(e.g. deictic/modal adnominals, deictic/state/property adnominals, infinite/modal adnominals, state/property/numeral adnominals).
