Is "the way how" grammatically incorrect?

Question

(I am not a native speaker so my writing probably seems to be odd. Please understand some Non-grammar...) I learned that "the way how" is grammatically wrong because 'the way' and 'how' have same meaning so it can stir up confusion or reduplication. And I can understand that explanation. BUT I think that if "the way how" is wrong, "the reason why" and "the time when" etc should be wrong, too. But I've NEVER heard and learned they are wrong too. I am really really confused... I can't understand why ONLY "the way how" is grammatically incorrect (or not). PLEASE help me... ( If you think that "the way how" isn't grammatically wrong and just unnatural expression, please give me reliable phrase... I'm not a native speaker so I can't realize what is unnatural spoken expression. )

Answer 1

How is generally a question word, such as How are you? or How are you going to get to the doctor today?

You are correct in assuming that way and how have similar meaning and it truly depends on the context.

Example: I do not know how to speak German OR I do not speak German. Another example: What is the best way to learn English?

It is grammatically wrong to state the way how, easily changing how to "to", for example, The way to achieve success is by working hard.

Hope this helps!
