Pronunciation

  • Brazil: /aˈtẽ.tu/[1]
  • Portugal: /ɐˈtẽ.tu/[1]

Forms

atento (feminine atenta, masculine plural atentos, feminine plural atentas, comparable, comparative mais atento, superlative o mais atento or atentíssimo)[1] Houaiss records atento, actento and atemto in the 15th century.[2]

Etymology

It is borrowed from Latin attentus (“attentive, heedful”), the past participle of attendō (“to stretch towards; to pay attention”).[2][3][1] Wiktionary calls it a learned borrowing and Nascentes a semi-learned one; the 15th-century spelling ⟨actento⟩ keeps a trace of the Latin ⟨-tt-⟩.[1][4][5] The Latin verb is formed ad- + tendō (“to stretch”).[6]

The same Latin participle is Spanish atento, Catalan atent, Italian attento and Romanian atent.[1] French built attentif on it with the suffix -if.[1][6]

Earliest recorded meaning

Houaiss dates the adjective to the 15th century.[2] In the CTA its first record is the Livro das tres vertudes a inssinança das damas, a copy made after 1450, and Lorenzo's chronology quotes the Frades Menores for cuidadossa e actenta “careful and attentive”.[7][8] The sense is already “paying attention, careful”.[8]

Semantic evolution

Machado's first quotation is from Os Lusíadas (1572), com olho atento “with an attentive eye”.[9] Morais (1789) refers atento to tento “care, attention” and quotes ir mui atento “to go very carefully”.[10] The old Aulete records the sense “respectful”, used in the closing formula of letters (seu atento venerador), and atento que “seeing that”.[11]

Modern dictionaries add “done with attention” (uma leitura atenta) and “taken into account, considered”, as in the absolute construction atenta a gravidade do caso “given the seriousness of the case”.[2][12]

Timeline
