Questions & Answers about Lisboa é um lugar grande.
Why do we use é instead of está here?
Why isn't there an article like a (the) before Lisboa?
In Portuguese, many cities and countries require a definite article (like o Porto or a França), but Lisboa is a famous exception. It is almost always used without an article.
Why is it lugar grande and not grande lugar?
In Portuguese, adjectives (descriptive words like grande) usually come after the noun they describe (like lugar). So instead of saying big place, you use the word order place big.
If the word for place was feminine, would grande change to granda?
