ABSTRACT
In the previous chapter, I have presented a unified account of the mo-presupposition. However, the mo-presupposition is only part of the meaning of mo. While the usage of mo indicates that the linguistic condition required for the usage of mo (i.e. the mo-presupposition) is satisfied or needs to be accommodated, it is not that the mo construction is used whenever this condition is present. In other words, the presence of the condition in which the mo construction can be used (so that the usage is contextually appropriate) does not necessarily warranty that the mo construction is used. Let us compare the following:
I: Kyoo no gogo wa nani shita no?
today GEN afternoon TOP what did FP
‘What did you do this afternoon?’
J: Watashi wa Macy’s ni itta no.
I TOP to went FP
‘I went to Macy’s.’
K: Watashi mo Bloomingdale’s ni itta no yo.
I too to went FP FP
‘I went to Bloomingdale’s, too.’
I: (= (la))
J: (= (1b))
K: Watashi wa Bloomingdale’s ni itta no yo.
I TOP to went FP FP
‘I went to Bloomingdale’s.’
