Arabic lesson No. 1: fenn. It means art, and it’s being uttered, printed and practiced like never before in Morocco’s “Jewel of the South.” From the narrow mazelike passages and bazaars of the old medina to the modern boulevards of the Gueliz district, a crop of new museums, galleries, gardens and indie creative spaces is showcasing the talents of Moroccan and international artists. The artistry is also spilling over into the city’s long-admired culinary and artisanal traditions, melding 21st-century materials and styles with classic Moroccan recipes and handwork. And with a continuing hotel surge, from new luxury palaces to renovated centuries-old private homes, the city is easier than ever to visit. Arabic lesson No. 2: Yalla! Let’s go!
