``보다`` 구성의 가정 의미기능 연구-``-아 봐``, ``-았어 봐``, ``-았단 봐``를 중심으로-

In this study, the subjunctive semantic function of the ``poda`` structure, which is used in particular conversational contexts, is examined. This study focuses on the usage of the subjunctive, which has not been the focus of much discussion to this point, by combining ``poda`` with other grammatical morphemes to form ``-a pwa``, ``-assa pwa`` and ``-attan pwa`` structures and examining the subjunctive semantic function and specifying its characteristics. The result is that the function of ``-assa pwa`` is ``Counterfactual conditionals`` that expresses a supposition of the opposite of what actually has happened, In addition, the subjunctive semantic function of the ``poda`` structure can primarily be seen in the face-to-face conversational context in the form of imperative in order to assume any situation, advise or counsel to someone by presenting a particular condition. This study especially focuses on the feature that ``-a pwa``, ``-assa pwa`` and ``-attan pwa`` structures are separate from the lexical meaning of main verb and function as the subjunctive constructions closely associated with a given context.
