Forms

rezonabil m or n (feminine singular rezonabilă, masculine plural rezonabili, feminine/neuter plural rezonabile)[1] Older spelling resonabil: „Un răspuns resonabil” “a reasonable answer”.[2][3] MDA2 also records a rare variant rezonabl.[3]

Etymology

It is borrowed from French raisonnable (“reasonable”).[4][3][5][2][1] The French word continues Old French resnable, from Late Latin ratiōnābilis, a derivative of Latin ratiō (“reason”).[1] Romanian has the older Latinate raționabil beside it, from the same Latin source.[6][7]

Earliest recorded meaning

Tiktin's first record is Pleșoianu in 1831, with the sense “sensible, reasonable”.[5] The DLR quotes Pleșoianu for the sense “moderate”: „Tu o iubești c-o dragoste rezonabilă” “you love her with a sensible love”.[2] MDA2 dates the word only from Negruzzi's writings of 1872.[3]

Semantic evolution

The word first described people who judge and act sensibly, then actions and decisions kept within normal limits.[2][4] In the 20th century it came to describe prices that match the value of the goods, and by extension prices one can afford.[2][3] Scriban in 1939 still marked it as a barbarism for raționabil, and the DLRLC of 1955 as a Gallicism.[6][8]

Timeline

  • 1831 – first record, in Pleșoianu.[5]
  • 1872 – in Negruzzi's collected writings: „Acei mai rezonabili judecau…” “the more sensible ones judged…”.[3][2]
  • 1939 – Scriban labels it a barbarism.[6]
  • 1955–1957 – the DLRLC labels it a Gallicism and records the sense “fair (of a price)”.[8]
