Numbers, the way
people actually say them.

Not a textbook drill — just the words you’d hear at a market stall in Madrid, said slowly enough to stick. Spanish and English side by side, no guessing.

Every number, both languages

Spanish word on top, English underneath — everything visible at a glance, nothing to tap or flip.

the round ones

Twenty, thirty, forty…

Once you know these, everything in between is just addition — veinte + uno = veintiuno (21). Scroll sideways to see them all.

going bigger

Hundreds, thousands, millions…

Past a hundred, Spanish just keeps stacking the same building blocks. Here’s where the words stop feeling new.

Two human tips: Spaniards run “veinti-” numbers together (veintiuno, veintidós…) but split every ten after that with “y” — treinta y uno, cuarenta y dos. And watch out for billón — it’s a false friend. In Spanish it means a million millions (10¹²), not the English “billion” (10⁹). What English calls a billion is mil millones in Spanish.
