glabrous

English

WOTD – 21 December 2021

Etymology

Pietro Perugino’s painting Don Biagio Milanesi, from the predella of the Vallombrosa Altarpiece (1500), depicts the glabrous abbot of the Vallombrosa Abbey in Tuscany, Italy.

The undersides of the leaves of the European crab apple (Malus sylvestris) are glabrous.

From Latin glaber (“smooth; bald, hairless”) + English -ous (suffix forming adjectives, denoting possession or presence of a quality in any degree, commonly in abundance). Glaber is ultimately derived from Proto-Indo-European *gʰleh₂dʰ- (“smooth; bright, shining”), possibly from *ǵʰelh₂- (“to shine”).
