- -esqueis a suffix forming adjectives, and corresponds to French -esque or Italian -esco (from the medieval Latin ending -iscus). In English it occurs in words derived from Italian and French, e.g. grotesque, picaresque, picturesque, and is an active suffix added to personal names to form adjectives meaning ‘in the style of…’, e.g. Audenesque, Disneyesque, Schumannesque, Turneresque. (It will be noticed that such words would only awkwardly make alternative forms in -ian).
