Use formal titles and surnames when addressing people you do not know well, especially older adults, professionals, and anyone in a service setting, and wait to be invited to use first names. In everyday Moroccan Arabic and French, respectful forms like
Sidi,
Lalla, Monsieur, and Madame are common, and in more traditional settings people may also use kinship-style terms such as
haj or
hajja for older men and women.
