Origin

Mid 16th century: from French masque, from Italian maschera, mascara, probably from medieval Latin masca 'witch, spectre', but influenced by Arabic masḵara 'buffoon'.

mascara from late 19th century:
Acting and clowning are indirectly linked in mascara, from Italian maschera, which goes back to an Arabic word meaning ‘buffoon’. Most of the earliest English uses refer to theatrical make-up, though the first known, from 1886, suggests a more discreet use by gentlemen: ‘For darkening the eyebrows and moustaches without greasing them and making them prominent’. Through Italian maschera mascara is also linked to mask (mid 16th century) and masquerade (late 16th century).

Rhymes
