Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Latin (sēmi-,ūrō)

Pronunciation

  • Classical: [seːˈmʊs.tʊs][1]
  • Ecclesiastical: [seˈmus.tus][1]

Forms

sēmustus (feminine sēmusta, neuter sēmustum); first/second-declension adjective[1] Also sēmiustus, the form under which the OLD enters it, scanned as three syllables.[2][3] Georges notes that the best manuscripts of Virgil, Livy and Tacitus have sēmustus.[3]

Etymology

It is from Latin sēmi- (“half”) + ūstus (“burnt”), the second part being the past participle of ūrō (“to burn”);[2][1][4] Wiktionary explains the contraction of /i/ and /u/ by comparison with sēmustulō.[1] De Vaan traces the verb to Proto-Italic *ouse/o- (“to burn”) and Proto-Indo-European *h1eus-e/o- (“to burn”), and compares Sanskrit ओषति (oṣati, “burns, scorches”) and Ancient Greek εὕω (heúō, “to singe”).[5]

Earliest recorded meaning

Köbler's first source is Cicero,[6] whom Georges cites for a half-burnt Typhon.[3] Lewis and Short call the form semustus not earlier than Augustus.[7]

Semantic evolution

It means half-burnt, scorched, singed.[2][7] Virgil has the body of Enceladus half-burnt by the thunderbolt and half-burnt timbers, Ovid a half-burnt torch, and Livy a half-burnt forum and statues.[7][3] Velleius Paterculus and Suetonius use it of half-burnt bodies, and Tacitus of the torn and half-burnt remains of houses and of half-burnt ashes.[7][3] Livy also uses it figuratively, of a man who said that he had escaped the people's fire half-burnt, that is, only just.[7][3][8]
