either

Number 2 is better.

"either" does not modify "goes" and so it's better to place it after it.
There is a potential other meaning.
For example, the first sentence could be extended thus:

"She either goes by bus or train, or drives there in her car."

But conversationally, in spoken English I mean, both are fine.

Re: either


My feeling is that the emphasis is stronger in number 1.

1. She either goes by bus or train! She is NOT hitchhiking, nor is she driving there with her friends!

2. She goes either by bus or train.

One more would work.

3. She goes by either bus or train.
