Okay, so let's talk about Spanish adjectives! Adjectives are words that describe nouns, like how in English we might say "happy dog" or "blue car." In Spanish, adjectives usually have to agree with the noun they describe in gender and number.
First off, gender: nouns in Spanish are either masculine or feminine. For example, "el perro" (the dog) is masculine, so if you want to say "the happy dog," you would say "el perro feliz." But if you're talking about a feminine noun like "la casa" (the house), you’d stick with an adjective that matches: "la casa feliz."
Then there's number. This means whether the noun is singular or plural. If you have multiple dogs, you say "los perros felices." You just add an -s if the adjective ends in a vowel or change the ending if it doesn’t.
Now, about where these adjectives usually go in a sentence: in Spanish, most of the time, adjectives come after the noun. So you'd say "la casa blanca" (the white house) instead of "la blanca casa." But sometimes, adjectives can come before the noun for emphasis or to change the meaning a bit. For example, saying "la gran casa" (the big house) puts a little extra importance on “big.”
Overall, just remember that adjectives need to match the gender and number of the nouns they describe, and they usually come after the nouns in sentences, but there are times when they can come first for effect!
