Subject pronouns + ser & estar
Portuguese verb endings already tell you who's acting, so subject pronouns get dropped all the time. You still need them — for emphasis, for clarity, and because você is the hinge the whole Brazilian verb system turns on. Today: the pronouns, and the full present tense of both 'to be' verbs, ser and estar.
The six person slots
Singular: eu = I; você = you; ele = he; ela = she. Plural: nós = we; vocês = you all; eles = they (men, or any mixed group); elas = they (women only). Here's the gift Brazil hands you: você and vocês are grammatically third person, so they borrow the ele / eles verb forms. That means a Brazilian present tense really has four shapes to learn, not six. One extra you'll hear constantly in the street: a gente = we, literally 'the people', with a singular verb — a gente está bem. Learn it as a listening word and keep using nós while the tables are still new.
tu vs você — the registers
In Brazil você is simply 'you'. It covers your best friend, your grandmother and your landlord; there's no separate intimate pronoun to unlock. When you need real formality you change the noun, not the pronoun: o senhor / a senhora. And tu? It survives in Rio Grande do Sul, in Pará and along parts of the Northeast coast — but even there most speakers attach it to the você verb form (tu vai, tu tá bem?) rather than the textbook one. Portugal runs the opposite way: tu everywhere, and você can sound cold. So learn one paradigm, use it across the whole country, and simply recognize tu when a gaúcho says it.
Ser — present tense
eu sou = I am. você é / ele é / ela é = you are / he is / she is. nós somos = we are. vocês são / eles são / elas são = you all are / they are. Chant it as four: sou, é, somos, são. Grammar books also print a tu form, és — you'll read it in a Portuguese novel or hear it in Porto Alegre, but you never have to produce it.
Estar — present tense
eu estou. você está / ele está / ela está. nós estamos. vocês estão / eles estão / elas estão. (The tu form is estás, same story as és.) The nasal -ão on são and estão is one of the signature sounds of Portuguese — push that air through your nose. Two very Brazilian facts: out loud, estou and está get clipped to tô and tá — tô bem, tá frio — and estar plus a gerund is how you say something is happening right now: estou falando = I'm speaking, ela está falando = she's speaking. That -ndo form is Brazil's; Portugal says 'estou a falar' instead.
When to use which
Use ser for identity, origin, profession, nationality, defining qualities and clock time: Eu sou brasileiro., Ela é médica., São três horas. Use estar for current location, current state, mood and weather: Estou em casa., Está frio., Você está bem? The quick test: if it will still be true next year → ser; if it could change by tomorrow → estar. Watch what the choice does to an adjective: Ele é frio describes a cold personality, while Ele está frio just means he's cold right now.
