A plural form of 'real,' the former currency of Brazil, or the captain of a ship in Portuguese-speaking regions.
From Portuguese real (royal), derived from Latin realis (relating to a king). The currency was named because it was stamped with a royal image.
The word 'real' (Brazilian currency) is still used even though the modern currency is called the 'real,' creating a fun linguistic loop where the old plural 'reis' appears in older texts!
