Plurals Practice exercises
If a noun ends in a vowel, add an -s
e.g.
un amigo - a friend, muchos amigos - many friends
una tortuga - a tortoise, dos tortugas - two tortoises
If a noun ends in a consonant, add -es
e.g.
un país - a country, varios países - various countries
una pared - a wall, cuatro paredes - four walls
Notes
If a noun ends in a -z, the ending changes to -ces to keep the 'th' sound; e.g. un pez - a fish, cincuenta peces - fifty fish
Compound nouns (verb + noun) do not change in the plural, e.g. el sacapuntas - the pencil sharpener, los sacapuntas - the pencil sharpeners; el abrelatas - the tin opener, los abrelatas - the tin openers.
When a noun is put into the plural, the stress still falls in the same place. Therefore, accents sometimes have to be added or alternatively removed; e.g. el joven - the young man, los jóvenes - the young men; un avión - a plane, dos aviones - two planes.
Masculine plural forms can contain both genders, e.g. los tíos - uncles or uncle and aunt, los reyes - kings or king and queen
