5. ORDINAL NUMBERS
Para saber los números ordinales tenemos que memorizar estas cuatro
primeras terminaciones:
1st (First) 2nd (Second) 3rd (Third) 4th (Fourth)
6. El resto de números ordinales, salvo el 11th, 12th o el 13th, se forman
añadiendo la terminación st si acaba en 1, la terminación nd si acaba
en dos o la terminación rd si acaba en 3. Para el resto, se les añade la
terminación th como en fourth = 4th.
