Pronunciation

Forms

crūdus (feminine crūda, neuter crūdum, comparative crūdior, superlative crūdissimus); first/second-declension adjective[1]

Etymology

It is from the root Proto-Indo-European *krewh₂- (“raw flesh, blood”), the root of cruor “blood”, but its formation is disputed.[1][2][3] De Vaan considers Proto-Italic *krowoþo-, from *kreuh₂-odʰ-o-, and mentions the alternative *kruh₂-ro- with an unusual change of ⟨r⟩ to ⟨d⟩, as in Avestan xrūra (“bloody”).[4] Cognate with Middle Irish crúaid (“hard, harsh”) and Old English hrēaw (English raw).[4][3]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[4][5] who has a cook complaining of people who serve raw vegetables.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant raw or uncooked, of food and of entrails offered without fire, and then untreated or crude, as of unbaked bricks.[2][6] Of food in the stomach it meant undigested, of wounds raw or bleeding, and of fruit unripe.[2] Virgil's crūda senectūs was a vigorous old age.[2] Of people it meant fierce or savage, and of pain or punishment bitter.[2]

Its derivative crūdēlis “cruel” gave English cruel, and crūditās meant indigestion.[1][7] English crude is from crūdus itself, first of coarse bread and untanned hide.[7] It survives in Italian crudo and French cru.[1]

Timeline

  • c. 250–184 BC – Plautus speaks of raw vegetables.[2][5]
  • 81–43 BC – Cicero says unripe apples can hardly be pulled from the tree.[2][5]
  • 70–19 BC – Virgil speaks of a green old age.[2][5]
  • late 14th century – English crude is recorded.[7]
