Forms

cheio (feminine cheia, masculine plural cheios, feminine plural cheias, comparable, comparative mais cheio, superlative o mais cheio or cheiíssimo, diminutive cheiinho, augmentative cheião)[1] Old Galician-Portuguese wrote chẽo and cheo (feminine chẽa, chea); the spelling cheio is recorded from the 15th century, beside chééo.[2][3][4] Morais (1813) still heads the word cheo and remarks that cheyo would be the better spelling.[5]

Etymology

It is inherited from Latin plēnus (“full”), written Old Galician-Portuguese cheo in the oldest texts.[2][3][4][6] It is the popular counterpart of the learned pleno, taken from the same Latin word.[2] The Latin /pl/ at the start of the word became /tʃ/, written ⟨ch⟩, as in other inherited words.[7] The old forms have no /n/ between the vowels, only a nasal vowel, marked with a tilde; the form with /j/ between the vowels is recorded from the 15th century.[2][4]

The same Latin word is Galician cheo, Spanish lleno, Catalan ple, French plein, Italian pieno and Romanian plin.[8][1]

Wiktionary traces the Latin adjective through Proto-Italic *plēnos to Proto-Indo-European *pl̥h₁nós (“full”), the source of Ancient Greek πλήρης (plḗrēs), Sanskrit पूर्ण (pūrṇa) and Old English full.[1]

Earliest recorded meaning

The Cantigas de Santa Maria of the second half of the 13th century have hũa nave… chẽa de romeus “a ship full of pilgrims” and o demo cheo d'enveja “the devil full of envy”; the troubadour Pedr' Amigo de Sevilha calls a man mui cheo de mal “very full of wickedness”.[4] In these records, as in most medieval ones, the adjective is followed by de and the thing that fills.[4]

Semantic evolution

The medieval texts use the word for vessels and places filled with something and, figuratively, for people filled with a feeling or a quality; the Miragres de Santiago have chea de graça “full of grace”.[4] The feminine became a noun, chea “a mass of water, a flood”, recorded in the Cantigas and surviving as cheia “flood, high water”.[9][8]

Modern senses extend the idea of fullness: “crowded”, “busy” (of a day), “plump” (of a person), “pregnant” (of an animal or, informally, a woman) and “drunk”.[2][10] In Brazil estar cheio is “to be fed up”, while in Portugal it is “to have eaten one's fill”.[2][11] As a noun the word names the thick stroke of a letter and, in music, the full sound of all the voices or organ stops together.[2][12] The word passed into Kabuverdianu as cheiu and txeu and into Guinea-Bissau Creole as tciu.[1]
