Curtis or Curtiss is a common English given name and surname of Anglo-Norman origin derived from the Old French curteis (Modern French courtois, surname Courtois) which means "polite, courteous, or well-bred". It is a compound of curt- ″court″ and -eis ″-ish″. The spelling u to render [u] in Old French was mainly Anglo-Norman and Norman, when the spelling o [u] was the usual Parisian French one, Modern French ou [u]. -eis is the Old French suffix for -ois, Western French (including Anglo-Norman) keeps -eis, simplified -is in English. The word court shares the same etymology but retains a Modern French spelling, after the orthography had changed.
It was brought to England (and subsequently, the rest of the Isles) via the Norman Conquest.
Many Hungarian immigrants in English speaking countries with the last name Kertész have adopted the name Curtis, since it is pronounced similarly and helped them integrate into their new community.
Curtis is a tiny lunar crater that lies in the western Mare Crisium, to the east of the crater Picard. It is a circular, cup-shaped formation that is otherwise undistinguished.
In the past it was designated Picard Z, before it was assigned an eponym by the IAU.
