I've mentioned in a different post that I always hear my in-laws referring to Geschäft in the same way as I would use the word "shop". I could be misinterpreting them though.
I've also heard them use the word Laden used in the context of storage area - for example, the small storage room beside a kitchen where one might keep sundries, floor brush, cleaners, etc..
I think that checks out - "aus" is a preposition that requires Dative and "Laden" is a neuter, and "einem'' is the correct article for a neuter noun in Dative case . . . but I'm not a native speaker and am relatively new to this, so . . . does anyone more experienced need to correct me here?
