I am confused about the meaning of the conjugations of [買]{か}う


I am on Livemocha and it says that 買います。 means "I am going to buy it." But I
figure that should be 買いに行きます。 . Also I know that ぎゅうにゅうを買っています。 is "I am
buying milk." But for some reason, I thought that ぎゅうにゅうを買う. could also mean
"I am buying milk." In short, I'm confused about when/how to use which
conjugation for what.




The basic form in Japanese like 買う・買います actually means both present tense and
future tense. The exact tense depends on usage. For example: 毎日ぎゅうにゅうを買います(I
buy milk everyday)・これからぎゅうにゅうを買います(I am going to buy milk) are using different
tenses despite using the same 買います.

The difference between 買います and 買いに行きます is not on tense, but on the focus.
買います focuses on the action of buying while 買いに行きます focuses on the action of
going (out). In most cases they can mean the same thing but in some cases no.
For example: ネットで株を買います(Buy stocks online) will never be said as
ネットで株を買いに行きます, as there is no "going out" action involved.

The difference between ぎゅうにゅうを買っています and ぎゅうにゅうを買う is that the first one is
present continuous while the second one is in future tense. A proper
translation would be "I am buying milk now" and "I am going to buy milk"

Sorry for the long answer.
