Bibliography
Marius Sala, De la latină la română
Univers Enciclopedic, 1998. The book that explains, for a reader who is not a linguist, why counting words in the dictionary and counting words in text give different answers.
Marius Sala (ed.), Vocabularul reprezentativ al limbilor romanice
Editura Științifică și Enciclopedică, 1988. The method for computing etymological weight over a representative vocabulary, of which the measurements here are a corpus-based variant.
Alexandru Ciorănescu, Dicționarul etimologic al limbii române
Romanian edition, Saeculum, 2001. One of the etymological sources aggregated by dexonline.
Alexandru Rosetti, Istoria limbii române
Editura Științifică și Enciclopedică, 1986. The reference for the older strata, from the substrate to Church Slavonic.
Alexandru Graur, Încercare asupra fondului principal lexical al limbii române
Editura Academiei, 1954. The first systematic demonstration, in Romanian, that the most-used core of the language is overwhelmingly Latin, however much the borrowings weigh in the dictionary.
