Counting in Spanish

Sep 10, 2025

Overview

This lesson covers counting in Spanish, including numbers from 0 to 1,000, patterns in their construction, special cases, and tips for practice.

Numbers 0–10

  • 0 is "cero" (replace 'z' with 'c').
  • 1–5: uno, dos, tres, cuatro, cinco.
  • Practice out of order to truly learn each number.

Numbers 11–15

  • All end with "-ce": once (11), doce (12), trece (13), catorce (14), quince (15).
  • "Qu" in quince makes a 'k' sound.

Numbers 16–19

  • Formed by combining "diez" (10) with the units: dieciséis (16), diecisiete (17), dieciocho (18), diecinueve (19).
  • "Dieci-" is a contraction of "diez y" (ten and).

Numbers 20–29

  • 20 is "veinte".
  • 21–29: use "veinti-" plus unit, e.g., veintiuno (21), veintidós (22), veintitrés (23).

Counting by Tens (30–90)

  • 30–90: treinta (30), cuarenta (40), cincuenta (50), sesenta (60), setenta (70), ochenta (80), noventa (90).
  • Combine tens and units with "y": treinta y cuatro (34), cincuenta y seis (56).

The Hundreds

  • 100 by itself is "cien"; otherwise "ciento" (e.g., ciento veinte).
  • 200–900: doscientos, trescientos, cuatrocientos, seiscientos, ochocientos.
  • Irregular forms: quinientos (500), setecientos (700), novecientos (900).

Combining Hundreds, Tens, and Units

  • Structure: [hundreds] + [tens] + y + [units], e.g., ciento noventa y nueve (199).
  • "Y" is only used between tens and units or in other large number combinations.

Other Key Points

  • Use regular number format to say years (e.g., mil novecientos noventa y tres for 1993).
  • Practice forming numbers for fluency.

Key Terms & Definitions

  • Cero — Zero in Spanish.
  • Cien/Ciento — 100 in Spanish; "cien" for exactly 100, "ciento" otherwise.
  • Y — The conjunction "and," used to connect tens and units.
  • Quinientos — Irregular form for 500.
  • Mil — Thousand.

Action Items / Next Steps

  • Practice numbers out of order.
  • Study spelling and pronunciation of irregular hundreds.
  • Prepare to combine numbers with months for future lessons.
