Etymology and origin of the Latin word siliqua

Confidence
Uncertain
First attested
116–27 BC, Varro

Pronunciation

  • Classical: [ˈsɪ.lɪ.kʷa][1]
  • Ecclesiastical: [ˈsiː.li.kʷa][1]

Forms

siliqua f (genitive siliquae); first declension[1]

Etymology

The origin is uncertain.[2][1] De Vaan lists it with silex (“flint”), but rejects the older derivation of both by dissimilation from an older ⟨skelik-⟩, and doubts that the flint word is related at all, since the meanings differ; he thinks silīgō (“soft wheat”) is close enough in meaning to come from the same root as this word.[3] Wiktionary considers a substrate origin likely,[1] while Köbler compares Proto-Indo-European *skel- (“to cut”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Varro,[3][4] whose farming treatise uses it of bean pods that have not yet grown enough for the beans to be picked.[2][5]

Semantic evolution

Its basic sense is a pod of beans and other pulses:[2][6] Virgil has a crop of pulse with rattling pods, and Columella and Pliny the Elder use it in farming.[2] In the plural it came to mean pulse as a cheap food: Horace has someone who lives on pods and second-grade bread, and Persius and Juvenal use it in the same way.[2][6]

Siliqua Graeca, or simply siliqua, is the carob tree or its fruit in Columella and Pliny the Elder, and siliqua Syriaca a kind of carob.[2][6] Columella also reports that country people gave the name to fenugreek.[2][7] In late writers it was a very small weight, one sixth of a scruple,[7][5] and in the Code of Justinian a coin worth one twenty-fourth of a solidus.[6][7] Medieval Latin used it as a weight of gold.[8]

British medieval writers used it for a husk or pod, often as the food of pigs, with reference to the prodigal son in the Gospel of Luke;[9] Bede writes of a pod that fills the body but does not nourish it, and it also stood for something worthless.[9] Italian serqua comes from it.[5]
