Forms
serios m or n (feminine singular serioasă, masculine plural serioși, feminine/neuter plural serioase)[1] The old variant serioz: „strălucind pe obrazul lor cel serioz o dulce și liniștită înțelepciune” “a sweet and quiet wisdom shining on their serious face” (Pleșoianu).[2][3]
Etymology
It is borrowed from French sérieux, with Italian serioso beside it, as Ciorănescu gives it.[4] MDA2 and Marcu add Latin seriosus, and Marcu & Maneca compare the Medieval Latin word.[4][3][5][6][1] Like many neologisms, it has several sources in the dictionaries.[3][4]
The French word was borrowed around 1370 from Medieval Latin seriosus, recorded from the 13th century, a derivative of serius (“grave, earnest”).[7] Wiktionary calls it a Late Latin formation with the suffix -ōsus.[1] The Italian word is recorded from Boccaccio, before 1375.[8] Nocentini compares the Latin adjective with Lithuanian svarùs (“heavy”) and Old High German swāri (“heavy, grievous”), so that its first sense was “heavy”.[9]
Earliest recorded meaning
The first record is in Molnar's translation of Millot's universal history (1800).[3] There a small thing gave the fickle people occasion for „petreceri serioase sau dinadinse” “serious or deliberate pastimes”.[2]
Semantic evolution
The first uses describe a grave, solemn manner, face or tone, as in Heliade's “her serious, calm voice” and Pelimon's “a serious face”.[2] Negulici's dictionary of neologisms (1848) still explains it: severe, not cheerful; true, done in earnest.[10]
Costinescu's dictionary of 1870 gives a luoa unŭ lucru în seriosŭ, la seriosŭ “to take a thing seriously”, with the French prendre au sérieux.[11] Later senses are “thorough, conscientious” of work and people, and “dangerous, grave” of an illness.[12][13]
