Questions & Answers about Os atores foram muito simpáticos.
Wait, I thought foram meant "they went". Does it mean "they were" here?
Yes! The verbs ser (to be) and ir (to go) share the exact same forms in the simple past tense. Because this sentence describes a characteristic (simpáticos), we know foram comes from ser and means "they were". If the sentence were about a destination, it would mean "they went".
Why is the plural of actor atores and not just ators?
Since atores and simpáticos are plural, shouldn't muito be pluralized to muitos?
Does the adjective simpáticos still have to match atores even though muito is in between them?
