The maun purpose of this study os review and analyze the differences, among clothing terms, between the biblical definitions of the underwear terms and those used by the public in day-to-day life. According, the biblical definitions of the underwear terms which are widely used by the various literature are summarized. Also, the degree of recognition of the underwear terms by the public is studied by analyzing the results of the questionnaires which are distributed to 217 female college students, as the objects of data, who reside in Seoul metropolitan areas. As a result of this study, we find the following conclusions : First, there are considerable differences in definitions of the underwear terms between those used by the various literature and those used by the public. The personal definitions of the underwear terms, or alternatively those used by the public, are very reduced and limited and even misunderstood in some cases. Second, the definitions of the underwear terms which are actually used by the public are recognized mostly by the wearing goals, the wearing spaces, the wearing times, the wearers, the forms and the materials and, among others, the wearing goals are the most dominating factor for the recognition of the underwear terms. Finally, the comparison among the similar underwears reveals that underwears are recognized by the wearing goals, the wearing spaces, the wearers, the forms and the materials. But, the objects of data recognize the underwear terms in very limited and simple fashion instead of having definite recognition of the differences among similar items.
