Ordinal numbers (Easy)
Vocabulary points to take away:
Ordinal numbers tell us the position of something in a group. They are used for:
It’s the twelfth of November
The order of events
Her fiftieth birthday
Position in space
Our apartment’s on the first floor
It’s the third on the right.
Order of quality
The first prize in the competition
We usually form ordinal numbers by adding -th to cardinal numbers:
four – fourth
first, second and third are irregular forms.
fifth, eighth, ninth, twelfth and numbers ending in -y have irregular spellings:
We say dates with the and of:
the eighth of April
April the eighth
But we don’t write them like that. We write them as:
first, second and third have the irregular suffixes 1st, 2nd and 3rd.
We usually use the definite article the with ordinal numbers:
on the third day
It was the first time I’ve ever been to France.
But sometimes we use possessives:
my thirtieth birthday
Julia’s second child
Ordinal numbers are also used as adjectives and adverbs without the or a possessive
