Forms

assistente m or f by sense (plural assistentes)[1]

Etymology

It is borrowed from Latin assistēns (“standing by, present”), the present participle of assistō (“to stand by, be present, assist in court”).[2][3][4][1] Nascentes takes it from the Latin spelling adsistēns by a semi-learned route.[5] Machado derives it instead from the Portuguese verb assistir, and thinks French assistance influenced some of its senses.[6]

The Latin verb is formed from ad- (“to, at”) and sistō (“to stand, be placed”).[1]

Earliest recorded meaning

Machado's first record is from 1449, in a text that names a Lugar-tenente, a Vix-Rei, a Governador or an Assistente who might be set over the kingdom.[6] Cunha dates the word to the 15th century, and Houaiss to 1541.[7][2]

Semantic evolution

The first dictionaries treat it as a legal term: Bluteau (1712–1728) defines the assistente as one who takes part in a lawsuit, with or without a power of attorney.[8] Morais (1789) gives “resident, dweller”, “the attorney in a case”, and the medico assistente who treats a patient regularly.[9] Morais (1813) adds the angels assistentes do trono de Deus and the assisting prelates at a bishop's consecration.[10] Vieira (1871–1874) quotes a sermon on os Serafins assistentes do throno de Deos.[11]

In modern Portuguese the main sense is a helper in someone's work, as in professor assistente and médico assistente.[2][3] Brazil has assistente social “social worker”, and the word can mean a midwife or a football linesman there.[12][13]
