Today we will learn about….

“Ser” and “Estar”: Two verbs for “To Be”

A lot of people can get confused with the verbs Ser and Estar, as these mean exactly the same - To Be.

So, how do you know when to use either?


1. The use of “Ser”

“Ser” denotes an inherent or permanent quality of ‘being’, for example: Sou um aluno ‘ I am a student’; Sou uma turista ‘I am a tourist’; Sou solteiro ‘I am single’.

In short, ser is what you are, or who you are. Here are some examples:

  • Sou Portuguesa. (f) I am Portuguese

  • Lisboa é linda. Lisbon is beautiful.

  • Ela é casada. She is married.

  • Nós somos amigos. We are friends.

N.B. ‘Ser’ plus the preposition ‘De’

Ser plus the preposition de denotes possession, origin. Although, to note that where there is a possessive adjective or pronoun, de is omitted:

  • Eles são de Londres. (They are from London)

  • Esta chave é do senhor Fernando. (This key belongs to Mr Fernando)

  • Esta cadeira é minha. (This chair is mine - possessive, therefore “de” is omitted).


2. The use of “Estar”

“Estar” is used when speaking of a temporary state or condition, action and place.

  • Nós estamos cansados. (We are tired)

  • Eu estou a trabalhar. (I am working)

  • Estou com fome. (I am hungry)

  • Eles estão em Londres. (They are in London)

Useful tip - if you are using the preposition “em”, you know that ‘estar’ must be used.


Other examples (Estar vs. Ser):

Ele está feio. (He is looking ugly - temporarily - “Estar”)

Ele é feio. (He is ugly - always - “Ser”)


3. Present Tenses of “Ser” and “Estar”

Examples with Ser and Estar:

  • (Você - formal) Fala Português?
