retina

See also: Retina, retinä, and retiña

English

Illustration showing parts of the human eye, including the retina.

Etymology

From Middle English rethina, borrowing from Medieval Latin rētīna (“relating to a net”, feminine), ellipsis of tunica rētīna (“net-like tunic”), used to describe the blood vessel system at the back of the eye. The phrase is attested in the 12th century in Guillelmus the abbot and Gerard of Cremona—the latter may have created this phrase as a translation for Arabic طَبَقَة شَبَكِيَّة‎ (ṭabaqa šabakiyya) "net-like layer", which translates Ancient Greek ἀμφιβληστροειδής χῐτών (amphiblēstroeidḗs khitṓn).

Latin

Etymology 1

Generally explained as from retineō (“to hold back, retain, restrain”) +‎ -a (agent noun suffix).

Classical Latin had the term retināculum n, which occurred almost exclusively in the plural (retinācula (“reins”)). This plural may have been reinterpreted as a diminutive feminine singular, then undergoing back-formation to form a non-diminutive retina.

Pronunciation

• (Classical) IPA^(key): /ˈre.ti.na/, [ˈrɛt̪ɪnä]
• (Ecclesiastical) IPA^(key): /ˈre.ti.na/, [ˈrɛːt̪inä]

Noun

retina f (genitive retinae); first declension

1. (Early Medieval Latin) a rein (strap or rope attached to a bridle or bit, used to control an animal)

     Apprehensaque equi Retina, celeriter eum Beneventum ducebat

     Having seized the horse's rein(s), he quickly rode it to Benevento.
