An arch that connects two houses and that passes under inhabited rooms.
This term is derived from Arabic, and is only used in the inland sicilian villages between Agrigento and Palermo, like Bivona, which is full of χanèe. The initial X Is pronounced with a guttural fricative /x/, as in the Greek letter Chi. Some other spelling versions are hanìa, hanèia, khanèa or canèia.

A close or pend in Scotland is the same, not necessarily with an arch but not exclusively so.
