níspero

medlar (Mespilus germanica, now Crataegus germanica); loquat (Eriobotrya japonica); sapodilla (Manilkara zapota and Manilkara huberi); great burnet (Sanguisorba officinalis)

Inherited from Old Spanish niéspero, néspero, from Vulgar Latin *nespirum, from Latin mespilum, borrowed from Ancient Greek μέσπιλον (méspilon), most likely of non-Indo-European origin. For the development of the stressed vowel, compare avispa (from Old Spanish biespa) and víspera (from Old Spanish viésperas).
