Hi!
Not sure this is the right forum.
I was looking into the etymology of the French word barbacane, which is a military construction with loopholes to facilitate shooting the enemy outside the city/fortress wall. The etymology would be in the Farsi word bârbâk-khaneh or bab-khanah . I wonder if this Farsi word really exists and if yes, which is the meaning.
Any advice is welcome!
