質問: もう と すでに はどう違いますか? もう と すでに はどう違いますか?
回答: すでに is only used when it is already established from a past time. もう can be used when not only it is already established but also it has just been established now. and すでに sounds objective than もう. すでに sounds it is a fact while もう can include an emotion (such as a surprise). for example: すでに5人のお客様が来ました。 (fact) もう5人のお客様が来ました。 (indicates that there are more than expected) もう5人目のお客様が来ました。 (the fifth client has been arrived. すでに can't be used in this case.)
