Pronunciation

Etymology

It is inherited from Latin hodiē (“today”); the Old Spanish form was oy.[2][3][4][1] The Latin adverb is a compound of hic (“this”) and diēs (“day”), literally “on this day”.[5][6][1] De Vaan takes the second part as an old ablative, and considers the form of the first part (bare stem, ablative or locative) impossible to decide.[5]

The word is common to all the Romance languages: Portuguese hoje, Galician hoxe, Asturian güei, Aragonese hue, Catalan avui, Old French hui and Italian oggi.[2][7][8][1] The Catalan form was vui or hui until fairly recently.[9]

In the earliest texts the word has two syllables, from a pre-literary *oje, as always in Berceo;[2][8] Aragonese and Leonese had the diphthong in huey and hué.[2][8]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, known from a 14th-century copy) has the word in the sense “today”: „cuando oy nos partimos, en vida nos faz juntar” “since we part today, bring us together again alive”, and „oy es dia bueno e meior será cras” “today is a good day and tomorrow will be better”.[10][11][2]

Semantic evolution

Because the word was so short, Old Spanish built an emphatic phrase hoy en este día, found in Berceo and the Libro de Alexandre, which was reduced to hoy en día and hoy día.[2] The modern language uses these two for “nowadays” and plain hoy for “today”, but in popular Argentine speech hoy día has replaced hoy altogether.[2] Old Spanish also had des oy más “from today on”, and Juan Ruiz uses d'oy mays for “at once”.[12][2]

The Academy's dictionary of 1817 records the proverb hoy venida, cras garrida, said of people made proud by their first stroke of luck, and the phrases hoy por hoy and antes hoy que mañana.[13] The DLE also gives a masculine noun, el hoy “the present”.[4] In Bolivia, Paraguay, Argentina and Uruguay de hoy en más means “from now on”.[14]
