Questions & Answers about A revista é interessante.
Why do we use é here instead of está?
Does the adjective interessante change if it describes a masculine word?
No, it stays exactly the same. Adjectives that end in -e in Portuguese, like interessante or grande, are usually invariable. This means they do not change to match masculine or feminine nouns. For example, you would use the exact same spelling in o livro é interessante (the book is interesting).
The word revista looks like the English word 'review'. Do they mean the same thing?
They are 'false friends'! In Portuguese, uma revista specifically means a printed or digital magazine. If you want to talk about a review of a book, movie, or restaurant, you would generally use the word crítica.
How would I change this to the past tense to match the current lesson?
To say 'The magazine was interesting' using the simple past tense (pretérito perfeito), you would say A revista foi interessante. Notice that the verb ser is highly irregular, so it does not use the regular -er past tense endings you are practicing in this specific lesson!
