Questions & Answers about O médico está em Lisboa.
Why does this sentence use está instead of é for "is"?
Why is there an accent mark on está?
The accent mark tells you to stress the final syllable when you say it out loud. It also helps distinguish it from the word esta, which has no accent, stresses the first syllable, and means "this" (for feminine words).
Why is it just em Lisboa and not na Lisboa?
The word em means "in". In Portuguese, some places require a "the" before their name, which makes em combine into words like no or na. However, most cities, including Lisboa, do not take a "the". Therefore, the preposition stays as just em.
