If the two nouns constitute separateitems, the usual rule applies and the
adjective is used in the plural:
una inteligencia y dedicación tremendas
tremendous intelligence and dedication
When a plural noun is qualified by adjectives which imply one of each, the
adjectives are singular:
los embajadores peruano y ecuatoriano
the Peruvian and Ecuadorian ambassadors
When an adjective precedes two or more nouns, it usually adopts the gender
and number of the first:
la extraña vida y aventuras de don Miguel
the strange life and adventures of don Miguel
When a compound adjective is formed with a hyphen, only the second of
the adjectives agrees with the noun:
discusiones hispano-marroquíes
Hispano-Moroccan discussions
Shortening of adjectives
The adjectives bueno‘good’ and malo ‘bad’, primero‘first’ and tercero
‘third’, uno ‘one’, ‘a’, alguno ‘some’ and ninguno ‘no’ drop the final -o
before masculine singularnouns.
In the case of algunoand ningunoa written accent is placed above the u
in the shortened form:
un buen libro a good book mal tiempo bad weather
el tercer día the third day ningún hombre no man
