Learn Portuguese (Portugal): O casaco preto é barato e bonito.

In Portuguese, adjectives that describe a noun—such as colors, shapes, or physical qualities—usually come after the noun they describe. So, instead of "black coat", you say "coat black" (casaco preto).

Why do the words preto, barato, and bonito all end in -o?

In Portuguese, adjectives must match the gender of the noun they are describing. Because casaco (coat) is a masculine word, all the adjectives describing it must also take their masculine singular form, which typically ends in -o.

How would this sentence change if we were talking about a feminine noun, like a shirt (a camisa)?

You would need to change all the adjectives to match the feminine noun. The sentence would become: A camisa preta é barata e bonita. Notice how all the -o endings change to -a to agree with the feminine word camisa.

Why does the sentence use é (from the verb ser) instead of está (from the verb estar)?
