Forms

sigur m or n (feminine singular sigură, masculine plural siguri, feminine/neuter plural sigure)[1] Molnar's grammar of 1788 spells it with sec-, after Latin secūrus.[2] MDA2 lists the old variants secur and segur and a regional secure.[3]

Etymology

It is borrowed from Modern Greek σίγουρος (sígouros, “sure, safe”), which comes from Venetian seguro or siguro, from Latin secūrus (“free from care; safe”).[4][1][5][6] The DLR and MDA2 give the Greek form as σέγουρος (ségouros).[7][3] Ciorănescu follows Cihac and Densusianu;[4] Cihac had first compared it with Latin and the Romance languages, and later took it straight from Greek.[8][9] The Greek adjective is medieval: Babiniotis derives it from Venetian, and the Latin from sē- (“without”) and cūra (“care”).[6][1]

The same Greek word gave Aromanian sigur.[10][11]

Earliest recorded meaning

Tiktin's first record is Molnar's German–Romanian grammar of 1788.[2] The DLR's oldest quotation, from the Carte trebuincioasă, speaks of „Sigure reguli” “sure rules” for each of the four operations of arithmetic.[7][3]

Semantic evolution

The first senses were “certain, beyond doubt” and “reliable”.[7][2] In 1848 a newspaper promised to print only „știri sigure” “reliable news”.[7] The sense “safe, free from danger” and the adverbial uses “certainly” and, as an answer, “yes, of course” followed.[12][2]

In the 18th century Romanian also borrowed the Greek verb as siguripsi “to make sure”, now obsolete.[4] The Romanian formations include siguranță “safety; certainty”, nesigur “uncertain”, asigura “to ensure; to insure” and desigur “of course”.[4][1] According to Wiktionary, Bulgarian borrowed сигурен (siguren) from this word.[1]
