「だろう」の意味考察 －不確かな捉え方をする推量の観点から－

Abstract

There is a use of presumption expression, in which a speaker indirectly understands the situation or the tableau based on one’s imagination or contemplation. The examples are as follows; (1b)　asitawa amega huruDAROO. What the sentence (1b) means is that it will rain tomorrow although it is not raining right now, and it lacks assurance. It means uncertainty for the speaker, and ‘DAROO’ lacking certainty grants the meaning of presumption. ‘DAROO’ to express presumption is for the estimation stemmed from indirect perception including imagination, contemplation or inference, regardless of whether it is accompanied with logical and certain evidences. Therefore, this inquiry concludes that it only enhances the level of conviction and never implies absolute assurance. Thus, the uses of ‘DAROO’ for ‘requesting confirmation and consent’ or ‘expressing doubt’, which are deemed to be derived from ‘DAROO’ for presumption, are as follows; In conclusion, ‘DAROO’ for ‘requesting confirmation and consent’ is used to express uncertainty although the speaker shares knowledge and information with the listener, while ‘DAROO’ of ‘expressing doubt’ is to reveal speaker’s vague perception of the situation, which includes unclear factors or lacks certainty of its establishment. Therefore, it is clear that both expressions are derived from ‘DAROO’ for presumption, in which the speaker conjures up the situation as an uncertainty.
