The Spanish word 'albino' comes from Medieval Latin 'albinus' meaning 'white or whitish', which itself derives from the Latin word 'albus' meaning 'white'. This etymological progression shows a straightforward development of the term used to describe the genetic condition characterized by the absence of melanin pigmentation.

Several common Spanish words share this Latin root 'albus', including 'alba' (dawn), 'albo' (white), and 'albura' (sapwood). These words all relate to the concept of whiteness or brightness. For example, 'alba' refers to the white light of dawn, while 'albura' describes the white, softer wood just under a tree's bark.

English speakers might recognize this etymology in words like 'albino' (which is the same in English), 'album' (originally referring to a blank white tablet), and 'albumen' (the white of an egg). The word 'Alps' is also believed to be related to this Latin root, referring to the white, snow-covered mountains.
