Questions & Answers about Las calles del casco antiguo son muy estrechas.
Why is casco antiguo translated as old town? Doesn't casco mean helmet?
Why do we use son instead of están here?
Is there a rule to know that calles is feminine, since it does not end in -a?
Nouns ending in -e (and their plurals in -es) do not follow a strict gender rule, so their gender simply has to be memorized. Because calle is feminine, we must use the feminine article las at the start of the sentence and the feminine plural adjective estrechas at the end so that everything agrees.
Why does the sentence use del instead of de el?
Whenever the preposition de is followed directly by the masculine singular article el, they must merge into the single word del. Because casco is a masculine singular noun, we use del to smoothly say of the without pausing between words.
