ABSTRACT
In this chapter, I will investigate the constraints on the usage of mo. Let me first state that mo does not have truth-conditional contribution to the propositional content of the sentence. In other words, a mo sentence and its alternative sentence without mo express the same propositional content. For instance, (2) and (3) below express the same propositional content as (1):
John wa New York ni itta.
John TOP to went
‘John went to New York.’
John mo New York ni itta.
John too to went
‘John went to New York, too.’
John wa New York ni mo itta.
John TOP to too went
‘John went to New York, too.’
