Forms
pau m (plural paus)[1] Old Galician-Portuguese wrote pao and, with a false doubled vowel, paao;[2][3] Houaiss records paaos in 1391.[2][3]
Etymology
It is inherited from Latin pālus (“stake, post”), written Old Galician-Portuguese pao in the oldest texts.[3][4][5][1]
The same Latin word is Galician pau, Spanish palo, Catalan pal, Occitan pal, French pieu, Italian palo and Romanian par.[6][7] Corominas notes that Spanish and Portuguese gave it senses, such as “wood” and “tree”, that the other Romance languages lack.[8][9]
The Latin noun is from Proto-Italic *pākslos, from Proto-Indo-European *peh₂ǵ-slos, a derivative of *peh₂ǵ- (“to attach, fix”);[1][10] Latin pangō (“to fix, drive in”) is of the same root.[1][10]
Earliest recorded meaning
Houaiss and Cunha date the word to the 13th century.[3][4] Lorenzo's chronology quotes the Fuero Real (se o ferir cũ pao “if he strikes him with a stick”) and a cantiga by Johan Velho de Pedrogaez, que vo-lo mande põer en hũ paao “that he have him put on a stake”, that is, hanged.[2][11] The Crónica Troiana has moytos paos ferrados “many iron-tipped staves” thrown in battle.[2]
Semantic evolution
Already in the medieval texts the word meant a stick or staff, a stake, a piece of timber, and the stick thrown in the knightly game of the tavolado.[2][11] Aulete's old dictionary has the wood itself as a material (colher de pau) and corporal punishment.[12] Its plural paus names the suit of clubs, which old packs of cards showed as staves.[5]
Many tree names are compounds with pau: pau-brasil gave its name to Brazil, and Silva Bastos lists dozens more.[13] In north-eastern Brazil, as in the Portuguese-speaking countries of Africa, pé de pau means any tree whose name is not known.[14] Modern Brazilian slang uses it for a unit of money (custou duzentos paus), for failing an exam (levar pau) and, vulgarly, for the penis.[12][1] The word passed into Kabuverdianu pó, Guinea-Bissau Creole po and Swahili pau.[1]
