Etymology
It is inherited from Latin sine (“without”), written Old Galician-Portuguese sen in the oldest texts.[2][3][1]
The same Latin word is Galician sen, Catalan sens and Old Spanish sen, a form not rare in medieval texts, especially Leonese and Aragonese ones.[4][5] Corominas finds the modern Spanish sin isolated in Romance, since the Latin word should regularly have kept its vowel e there.[4] The REW treats French sans and Italian senza separately, and Wiktionary explains the French word as the Latin word blended with absentia.[6][1]
De Vaan reconstructs Proto-Italic *sn(H)i and Proto-Indo-European *sn̥h₁-i, perhaps a locative, and compares Ancient Greek ἄνευ (áneu, “without”), Old High German suntar (“without”) and Tocharian B snai (“without”).[7] Wiktionary gives the root as *sene and notes that older Latin expressed “without” with sē.[1]
Earliest recorded meaning
The Cantigas de Santa Maria use sen freely: morreu sen confisson “he died without confession”, sen aver pitança “without having a pittance”, and many fixed phrases such as sen dulta “without doubt” and sen demora “without delay”.[8] In the Cancioneiro da Ajuda it forms adjective phrases equivalent to a prefix of privation, such as sen mesura, sen ventura and sen sabor.[8]
Semantic evolution
Medieval texts also use it for “apart from, besides” and, in the cantigas d'amigo, for “except, unless”.[8] Viterbo found it used for “not” in old documents, as in sem declarando “not declaring”.[9] Morais describes it in 1789 as a preposition of exclusion before a noun or a clause.[10]
From the 19th century sem also works as a prefix for privation, as in sem-vergonha and sem-terra.[11] The word passed into Macanese as sim and into Ambonese Malay as seng.[1]

Usage notes
Common fixed phrases are sem dúvida “certainly”, sem mais nem menos “for no reason, suddenly” and sem tirar nem pôr “exactly”;[16][15] sem que introduces a clause in the subjunctive.[16][15] Sem sounds the same as cem “hundred”.[15][17]
The cantigas also have a noun sen or sem “sense, judgement”, as in perdi o sem e a razom “I lost my sense and reason”, in a cantiga of Dinis;[18][8] Michaëlis derived it from Old Occitan sen.[18][8]
