+ It is [[bor|grc|θησαυρός|tr=thēsaurós|t=treasure, storehouse]].^(OLD 2012)^(Saalfeld 1874)^(Wiktionary) Etymonline reports two views of the Greek word: Watkins connects it with a reduplicated form of [[ine-pro|*dʰeh₁-|t=to put]], while Beekes takes it as a technical loanword.^(Etymonline) The older Latin spelling is [[m|la|thēnsaurus]], with an inserted /n/.^(OLD 2012)^(Georges 1913)

+ It was a store or hoard of precious things, often buried or hidden, and also the place where valuables were kept, a treasure chamber or vault.^(OLD 2012)^(Gaffiot 2016) Plautus uses it figuratively for a great store of something, and a pimp in the Curculio calls a person ''thensaurus meus'' “my treasure”.^(Gaffiot 2016) An inscription names a keeper of the treasuries, and Petronius has a neuter form ''thesaurum''.^(Lewis & Short 1879)^(OLD 2012)
+
+ In medieval Latin it was ready money and the royal right to treasure found, treasure trove.^(Niermeyer 1976)^(Köbler 2010) British writers used it of a storehouse or repository of knowledge.^(DMLBS) English ''thesaurus'' is recorded in 1823 as “treasury, storehouse”.^(Etymonline)
