A1 (Beginner)Lesson 3: Present Indicative & Modal Verbs
Portuguese has two verbs meaning "to be" – ser and estar – each with distinct uses and completely irregular conjugations that must be memorized.
Ser = identity, profession, origin, defining qualities, belonging, time & dates.
Estar = location, temporary states, feelings, ongoing actions.
Ser: sou, é, somos, são · Estar: estou, está, estamos, estão (a gente → é / está).
A few adjectives switch meaning: ser bom (be kind) vs estar bom (be well / taste good).
Location uses estar — but an event's location uses ser: A festa é no clube.
Both verbs are completely irregular — memorize them.
Ser and estar turn up in almost every sentence you'll say in Portuguese — introducing yourself (Sou brasileiro), asking how someone is (Como está?), or finding the bathroom (Onde está o banheiro?). English uses a single "to be" for all of this, so the real work for an English speaker is building the reflex to ask: am I saying what something is (ser), or how/where it is right now (estar)? Pick the wrong one and the meaning can flip — ser with a place can make it sound like the person is that place instead of being at it. Get the habit early and you can describe people, feelings and locations from your very first conversations.

Portuguese splits the English verb "to be" into two. Ser is for what something fundamentally is; estar is for how or where something is right now.
SER — identity / essence
eu sou
você / ele / ela é (a gente é too — see Lesson 2)
nós somos
vocês / eles / elas são
(tu és — rarely used in Brazil)
"Sou John. Sou americano." (I'm John. I'm American.)
"Ela é médica." (She's a doctor.)
"Nós somos brasileiros." (We're Brazilian.)
"Você é professor?" (Are you a teacher?)
"Como está?" (How are you?)
"Estou bem, obrigado." (I'm well, thanks.)
"Estou com fome." (I'm hungry.)
"Ela está doente." (She's sick.)
Ser feliz = to be a happy person in general: Sou feliz.
Estar feliz = to feel happy right now: Estou feliz hoje.
Even though it's about as permanent as it gets, Portuguese uses estar:
Ele está morto. (He is dead.) — never é morto.
The weather right now → estar: Hoje está frio. (It's cold today.)
The general climate → ser: O clima do Rio é quente. (Rio's climate is hot.)
From "to sit" and "to stand": estar comes from the Latin verb stāre ("to stand"), while ser grew out of esse ("to be") blended with sedēre ("to sit"). That ancient contrast — settled, seated permanence vs. where you currently stand — still echoes in ser for lasting essence and estar for the present moment. (Universidade NOVA de Lisboa)
Brazilians swallow the "es-": in everyday Brazilian speech estar almost always loses its first syllable — estou → tô, está → tá, estamos → tamo. A standalone "Tá?" is also one of the most common ways to say "OK?", so you'll meet this verb long before you've finished memorising it. (Transparent Language)
