Forms

livro m (plural livros, diminutive livrinho, augmentative livrão)[1] Old Galician-Portuguese wrote livro and lyvro;[2][3] Houaiss also records libros in the 15th century.[2][3]

Etymology

It is borrowed from Latin liber (“bark of a tree; book”), written Old Galician-Portuguese livro and Old Galician-Portuguese lyvro in the oldest texts.[2][4][3] Wiktionary treats it as an early borrowing of the Latin accusative rather than an inherited word, and Corominas finds a learned form of the word in every Romance language: Spanish libro, Italian libro, Catalan llibre, Occitan libre and French livre.[1][5]

In Latin the word first meant the inner bark of a tree, which the Romans used to write on, and then “book”.[6][7] It goes back to *luβros and Proto-Indo-European *lubʰ-ró-s, meaning “leaf, rind” according to de Vaan, from the root *lewbʰ- (“to peel”).[6][1]

Earliest recorded meaning

Houaiss quotes a doubtful record of liuros in a Latin document of 1013.[2] In the Cantigas de Santa Maria the word is a written book: the Virgin gives a man un lyvro, a devout man reads a whole large book every day, and the collection itself is o livro das Cantigas de Santa Maria.[3]

Semantic evolution

Bluteau already explained the word from the Latin name of the inner bark on which people once wrote.[8] Morais (1789) adds the sense “part of a work”, the division of a long text, and the registers of the king's household, livros d'el-rei.[9] Aulete's original dictionary has the figurative “anything that teaches like a book”, as in o livro da natureza, and the commercial account book.[10] Silva Bastos (1912) records the anatomical sense, one of the stomachs of ruminants, the omasum, named after its leaf-like folds.[11][1] In Rio Grande do Sul the livro of a ranch is the register of the cattle and of the sales.[12]

The word passed into Kabuverdianu as libru and into Tetum as livru.[1]

Timeline

  • 1013 – liuros in a Latin document, a doubtful record.[2]
