Pronunciation

  • Brazil: /ˈla.kɾi/[1]
  • Portugal: /ˈla.kɾɨ/[1]

Forms

lacre m (plural lacres)[1] Old forms are lacra (1498), llacre (1525) and alacre (1563).[2]

Etymology

It is a variant from Portuguese laca, the name of the resin, which is an important part of sealing wax.[2][1][3] Nascentes, Aurélio and the DLP derive it from an older lácar with an added -r.[4][5][6] Corominas also takes this to be the oldest form but calls the origin of its -r uncertain.[3] Houaiss, following Dalgado, treats both as divergent forms of one word that tend to divide its meanings.[2][7] The source of that word is Arabic لك (lakk), through Persian from Sanskrit लाक्षा (lākṣā).[7][1]

Spanish lacre (1572) was borrowed from Portuguese.[8][9]

Earliest recorded meaning

Houaiss's first record is lacra in the journal of Vasco da Gama's voyage of 1498, which notes that the land has much lac.[2][10] The form lacre follows in 1508, in a letter in which the viceroy Francisco de Almeida tells the king how hard it will be to send the lacre he wants.[2][10]

Semantic evolution

At first lacre named the resin itself, much of it from Pegu: a list of goods shipped from Goa in 1630 has lacre de canudo, lacre de formiga and lacre vermelho.[10] Bluteau (1712–1728) still describes it as a gum made in India from the sap that winged ants leave on trees.[11] Pereira's Thesouro of 1697 already glosses it as sealing material, and Morais in 1789 defines it as a mixture of gums used to close and seal letters, sold in sticks.[12][13]

In Brazil it also names trees whose cut bark gives a red sap, a scrubland of the north-east and, in Minas Gerais, red jasper, named for its colour.[2][4][14] Today it is also the seal of a container or meter that shows whether it has been opened.[1] The word was borrowed into Spanish, and Wiktionary lists Malay lakri and Swahili lakiri as loans from it.[1]
