[Grammar] come from

[KJOU]

Which way did you come?

Do I should put the "from" at the end of the sentence?

 

[emsr2d2]

No, you shouldn't. "Which way did you come?" means "Which route did you take?" If you want to use "from" at the end, you need to say either "Where did you come from?" or "Which direction did you come from?" Neither of those mean the same as your original question.

 

[KJOU]

(1) Which way did you come from?
(2) Which direction did you come from?

They look identical to me. Could you tell me why I can't use "from" in the sentence (1)?

 

[jutfrank]

Which way did you come?

The word way means 'route'. The question is equivalent to Which route did you take? A route is a way from A to B. This idea of 'from/to' is implicit within the meaning of the words way/route.

 

[emsr2d2]

(1) Which way did you come from?
(2) Which direction did you come from?

They look identical to me. Could you tell me why I can't use "from" in the sentence (1)?

How can they look identical? One uses "way" and the other uses "direction". They are clearly not identical. Take care with how you use words. If you mean "I think their meanings are identical", that's what you should say.
