Use "zaguan" in a sentence
""zaguan," running through the breadth of the building, and then we are in the patio."
"Since a "great house" which has been converted into a small museum is the architectural example that visitors are most likely to see, we'll try to capture some of their elegance: A doorway on the street leads to a rather dark passageway, called the zaguan."
"From the vestibule main entrance (_zaguan_) one passes to the upper floor, which constitutes the house proper, where the family resides."
