Question

He won his battle against British
Chang into plural​

Answer 1

Singular :

• He won his battle against British.

Plural :

• They won their battle against British

Answer 2

To change singular nouns to plural nouns, you add an -s if the ending letter is a vowel. If the last letter is a consonant, you add -es.

To change plural nouns to singular nouns, you remove the -s or -es.

To change "las casas", a plural noun, into a singular noun, it would be "la casa".

Therefore, the singular form of "las casas" is la casa.
