Etymology

It is borrowed from Medieval Latin praeambulum (“preamble”), the Late Latin adjective praeambulus (“walking in front, preceding”) used as a noun.[2][1][3] Houaiss derives it directly from the adjective, and Nascentes calls it a learned word.[2][4] Lewis and Short mark the adjective as post-classical, with examples from Martianus Capella, and the DHLF dates it to the 5th century.[5][3] In Medieval Latin it also meant “previous”, and as a masculine noun “forerunner” or “guide”; the neuter noun was the text placed before a legal or official act.[6][3]

The adjective is formed from praeambulō (“to walk in front”), itself from prae- (“before”) and ambulō (“to walk”).[1] Bluteau already explained the word as made of these two Latin parts.[7] The verb goes back to *alā- (“to wander”), according to de Vaan;[8][1] Wiktionary analyses it as ambi- and a verb *alō, from Proto-Indo-European *h₂elh₂- (“to wander”).[8][1]

The same Medieval Latin word gave French préambule (1314), Italian preambolo, Spanish preámbulo and Romanian preambul.[3][9][1]

Semantic evolution

Houaiss dates the word to the 15th century, from Cunha's slips of medieval Portuguese, while Cunha's own dictionary dates it to the 16th.[2][10] The early dictionaries define it as the opening of a speech: Bluteau gives “preface, exordium” and remarks that people who ask for a loan make long preambles before they strike, and Feijó (1734) glosses it as the beginning or exordium of a discourse.[7][11] The old Caldas Aulete adds the legal senses, the report placed before a law and the part of a decree in which the sovereign announces its promulgation.[12]

From the introduction the word passed to any roundabout talk that delays the main point, often in the plural.[2][13] In music it is used for a prelude.[2][14]
