From the same root
Pronunciation
- /tɾanˈkilo/, [t̪ɾãŋˈki.lo][1]
Forms
tranquilo (feminine tranquila, masculine plural tranquilos, feminine plural tranquilas)[1]
Etymology
It is borrowed from Latin tranquillus (“calm, still”).[2][3][4][1] The BDELC dates it about 1440; the DCECH cites the Marqués de Santillana, then Góngora in 1582, and finds it common in the Quijote.[2][3] The noun tranquilidad, from tranquillitās, is also recorded about 1440.[2][3]
The Latin adjective is perhaps formed from trāns (“across”) and the root of quiēs (“rest”).[5][1] De Vaan finds this etymology, with a root Proto-Indo-European *kʷih₁- (“to be quiet”), vague in meaning and doubtful in sound, since the change of *-nskʷ- to -nqu- is disputed and the suffix unclear.[6] The same Latin root gives quieto and quedo.[3]
Earliest recorded meaning
The first record is in the Marqués de Santillana, about 1440.[3][2] The word was rare at first: the Old Spanish Textual Archive has only eleven examples, from 1484 on, and Covarrubias and Cristóbal de las Casas list only tranquilidad.[7][3]
Semantic evolution
Cervantes uses it of the sea and of a peaceful life: mar tranquilo, en paz tranquila.[8] The Diccionario de Autoridades defined it as “quiet, calm, peaceful” and, by analogy, of a mind not disturbed in its peace and security.[9] The DLE now adds a person who takes things calmly, without hurry or nerves, and does not care what others think, a sense that Moliner also records as a noun.[4][10]
As an interjection, ¡tranquilo! means “calm down!”.[1][10] In Venezuela tranquilo is popular for “drunk”.[11]
