Pronunciation

  • IPA (Ecclesiastical): [ˈsik.kus][1]

Forms

siccus (feminine sicca, neuter siccum, comparative siccior); first/second-declension adjective[1]

Etymology

It may be inherited from Proto-Italic *siskwo-, inherited from Proto-Indo-European *si-sk-u- (“dry”), from a root *sek- “to dry up”.[2][1] Cognate with Middle Irish sesc (“dry, barren”), Avestan 𐬵𐬌𐬱𐬐𐬎 (hišku-, “dry”) and Middle Welsh hysp (“dry”), but how this gave the double /kk/ is unclear, so the etymology is uncertain.[2][3] Ernout and Meillet and Pokorny instead connected *seikʷ- “to pour”, as “lacking water”, which de Vaan finds awkward.[2][4]

Earliest recorded meaning

De Vaan dates it from Cato, who says grapes for wine should be gathered ripe and dry.[2][3] Köbler dates it from Plautus.[4] Köbler dates Cato 234–149 BC.[4]

Semantic evolution

It meant dry, free from moisture, as dry hands and dry sand, and of hair not anointed.[3][5] In medicine it described conditions without discharge, as a dry cough, and dryness as a sign of health.[3] Things lacking their natural moisture were dried up, the dry element among the four, dry winds and air, and liquids dried up.[3] Figuratively it meant sober, “dry” of drink, and of style plain and sober, as Cicero's sound and dry orators.[5][6]

Döderlein contrasts siccus, dry outside, with āridus, dried within.[7] It survives in Italian secco, French sec and Spanish seco, and dēsiccāre gave English desiccate in the 1570s.[1][8]
