Forms

subiectus (feminine subiecta, neuter subiectum, comparative subiectior); first/second-declension adjective[1] Seneca scans it as four syllables, sŭbĭect-.[1] It is also spelled subjectus.[2][3]

Etymology

It is the participle of subiciō (“to throw under, place under”), used as an adjective.[1][2][3] That verb is sub- (“under”) with iaciō (“to throw”), which de Vaan traces to Proto-Italic *jak-i- (“to throw”) and a present Proto-Indo-European *(H)ih₁-k- (“to throw, let go”).[4] Cognate with Ancient Greek ἵημι (híēmi, “to send, throw”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[5] who in a letter to his brother writes of a heated room placed beneath the bedrooms.[1]

Semantic evolution

It means lying under or lower, and also close at hand or adjacent, as a country bordering a kingdom in the Bellum Alexandrinum.[1] Cicero uses it of things within the reach of the senses and of a sea exposed to the winds; later it is liable to a tax.[1] Apuleius has subiecta materia, matter subject to shaping, a translation of Aristotle's term for matter.[1] It also means subordinate or subject to a person or state, as Livy's “let us be as subject as the Thessalians and Aetolians”;[1] Columella uses the masculine as a noun for subordinates, and Ovid of a submissive bearing.[1] In rhetoric it is placed under a heading.[1]

In medieval Latin it means submissive, obedient or subjugated, and as a noun a subject, dependant or assistant.[6] English subject (early 14th century, via Old French) comes from the noun use of the Latin participle.[7]
