noun, masculine/ˈlustɾe/plural: lustres
lustre, shine
“el lustre de mis zapatos, del metal, de los minerales” — the shine of my shoes, of the metal, of minerals
Related: azúcar de lustre
From either French lustre or Catalan llustre, from Italian lustro, derived from the verb lustrare. A French or Catalan intermediate is likely due to the change in the final vowel, typical of borrowings that are ultimately early Italianisms before the 16th century. Not attested in Old Spanish; first attested in Nebrija.
