Etymology
It is inherited from Latin quem (“whom”), the accusative of the Latin interrogative pronoun, written Old Galician-Portuguese quen in the oldest texts.[2][3][1] Wiktionary and Nascentes also connect it with the relative quī (“who”).[1][4] Houaiss lists the forms Old Galician-Portuguese que and ⟨quen⟩ in the 13th century and the modern spelling in the 14th.[2] The REW notes that the Romance outcomes of the Latin accusative serve as nominatives as well, except in Logudorese Sardinian.[5]
The same Latin form is Spanish quien and Romanian cine.[5] Old Portuguese also had Old Galician-Portuguese qui, from the Latin nominative.[5]
The Latin pronoun goes back to Proto-Italic *kʷis, from Proto-Indo-European *kʷis.[1][6]
Earliest recorded meaning
Houaiss dates the pronoun to the 13th century and the phrase quem quer que “whoever” to 1214.[2] The DDGM's glossary of a medieval Galician chronicle lists quen far more often than quem, both as a relative and as an interrogative.[7]
Semantic evolution
Barbosa's dictionary of 1611 already has proverbs built on quem, such as Quem tolo vay a Santarem, tolo vem “whoever goes to Santarém a fool comes back a fool”.[8] Bluteau notes that quem, like qual, could ask about only two persons, where Latin used uter.[9] Morais (1789) points out that quem is also used for the plural, as in quem serão pais destes meninos?.[10]
Beside the interrogative and relative senses, modern Portuguese uses it as an indefinite pronoun (“someone who”), and in quem dera! “if only!”.[2][11] The proverb quem com ferro fere com ferro será ferido “whoever wounds with iron will be wounded with iron” is still current.[12]
