When to use "por."
Do I always use "por" when talking about location?
Would I say, "Camino por la ciudad" or "Camino en la ciudad" ?
Camino por la ciudad. = Most likely meaning is "Road through the city"
Camina para la ciudad = Most probable meaning is "Road to the city", and
Camino a la ciudad = Most likely meaning is "Road to the city".
Camino por la ciudad would be correct in this instance. Por would relate to "through," "along," "by" or "in the area of".
I believe you would. You can check out the following link, it explains the usage of por.
