Can someone explain what, Le chien marche depuis la-bas, means to say? Because if it means to say, The dog walks from there, I would think they could just say, Le chien marche de la, or, ....depuis la, or, .....de il y a?
Why, depuis, instead of, de? And why, la-bas, instead of just la? Also Duo say that french sentence also means, .....from here?
I've been speaking french since I was six and never heard 'depuis' used spatially. That doesn't mean it's impossible, but it's certainly not common if it is correct.
I thought "depuis" was a temporal preposition like "since," e.g., "depuis qu'il est grand." Here it seems to be used as a spatial preposition.
Both are correct. It is used as a starting point in a spatial or temporal configuration.
