Questions & Answers about Ella cantó en el coro ayer.
Why is the accent mark on cantó so important?
The accent mark changes both the pronunciation and the meaning! cantó (with the stress on the last syllable) means she sang in the past tense. If you remove the accent, canto (with the stress on the first syllable) means I sing in the present tense.
How do we know to use this specific past tense for this sentence?
Could I drop the word ella and just say Cantó en el coro ayer?
Is the r in coro rolled like a double rr?
No, because it is a single r in the middle of a word, it is a short tapped sound. This sounds very similar to the quick d or t sound in the middle of the English word butter. You do not want to roll it, because corro with a rolled rr means I run!
