Disci

Disci is the Latin plural form of the noun discus. In classical Latin grammar, disci serves as both the nominative plural of discus and the genitive singular, reflecting the language’s declension patterns. Because of this, disci appears in scholarly Latin writings and in modern discussions that preserve Latin terms in scientific and academic contexts.

In anatomy and biology, disci frequently shows up in phrases describing disk-shaped structures. For example, in Latin-language anatomical terminology one might encounter disci intervertebrales to refer to the intervertebral discs, along with other disc-like formations described using the plural or combined with descriptive adjectives. The term thus functions more as a grammatical form than as a standalone English term.

In modern usage, disci is largely confined to historical, philological, or quotation contexts. English-language writing normally uses discs or disks for the plural of disc, reserving the Latin plural disci for quotations, taxonomic names, or texts that aim to preserve classical terminology. In mathematics and geometry, older or scholarly texts may also employ disci to denote disk-shaped figures, though contemporary terminology typically favors disks or disks.

Overall, disci is primarily encountered as a Latin plural form rather than as an independent concept in English, with its relevance mainly in linguistic, historical, and Latin-quoted contexts.
