Brazil's Currency Is the Real, Not the Riyal

Common confusion, but they're completely different:

• Brazil: Real (BRL) — symbol R$, plural reais. Subunit: centavo (100 = 1 real).
• Saudi Arabia: Riyal (SAR) — symbol ﷼ or SR. Subunit: halala (100 = 1 riyal).
• Also using "riyal": Qatar (QAR), Oman (OMR), Yemen (YER).

The words share an etymological root (Spanish real = "royal"), but they've been distinct currencies for centuries. Brazil's real was introduced in 1994 (Plano Real) to end hyperinflation; Saudi Arabia's riyal dates to 1925 (Hejaz) and was unified in 1935.
