Analyses of English Derivatives Attached with Negative Prefixes

－ inadvisable / unadvisable －

抄録

This paper aims at presenting how different negative prefixes have been employed for producing a new word for a long time. In order to investigate the frequency of occurrence of the targeted derivatives, some corpora will be of great importance. In addition to the corpora, dictionaries will be used for the definitions of the words not only in Present-day English but also in the past.
