In Portuguese, I can ask literally "Por onde vais?" meaning something like "What is the path you are taking?" I would like to know how to ask this in English, using "where", possibly a preposition (by, through etc.) and possibly the verb "TO GO". Is there such a question structure in English? Many thanks.
You could ask:
What path are you taking? - to get from A to B
What is your path? - where path means the route between two places. I would not normally use 'path' in the literal sense and would normally ask "What route are you going to take?" - to get from A to B, or less formally
How are you going to get there? - Depending on context, this could be asking about either the specific route - to get from A to B or the specific mode of transport (Car / bus / Train) the person intends to use to get from A to B.
