Aprende los números ordinales en inglés del 1.º al 20.º con ejemplos reales
Los números ordinales en inglés permiten hablar de fechas, posiciones y turnos. Desde first hasta twentieth, son esenciales para entender frases como «the second floor» o «the fifteenth birthday party». Aprenderlos desde el inicio te ayuda a comunicarte con mayor precisión y naturalidad.
A diferencia de los cardinales (one, two, three), los ordinales indican orden o secuencia. Son clave para decir tu cumpleaños, hablar del piso donde vives, numerar visitas o describir episodios de una serie. En esta lección verás cómo se usan en contextos reales que reflejan la vida cotidiana.
Los ejemplos están diseñados para principiantes. Cada diálogo presenta una estructura simple y clara donde aparece un número ordinal acompañado de verbos comunes como is, have o visit. Así podrás memorizar la forma correcta, su pronunciación y su uso natural en conversaciones.
Gramática clave
Los números ordinales en inglés terminan en -th, salvo algunas excepciones:
1st: first
2nd: second
3rd: third
A partir del cuarto, la mayoría siguen el patrón: fourth, fifth, sixth, hasta twentieth. Se usan con artículos definidos como the, y en estructuras como:
Today is the tenth of the month.
This is my twelfth visit.
He is the eleventh student on the list.
Se escriben también con abreviaciones numéricas: 1st, 2nd, 3rd, 4th, etc. Estas formas son comunes en calendarios, listas, correos y formularios.
