Overview
if? Isso é porque o inglês tem um truque de magia porreiro a que chamamos inversão.if para frases de talvez. If you go, I will go. Mas às vezes, deitamos fora o if e trocamos as palavras. É como um código secreto para ser formal.Had I known he was a liar... soa muito mais poderoso do que If I had known. É uma ótima forma de mostrares que estás a falar a sério.if é simplesmente aborrecido. Queremos parecer inteligentes numa chamada de Zoom ou profissionais numa entrevista de emprego.Word Order Rules
if, seguimos um caminho simples: if + Sujeito + Verbo. Por exemplo: If you should see her.... Para fazeres a troca mágica, seguimos duas grandes regras.if para o lixo. Não precisamos dela! Segundo, movemos o verbo auxiliar (Should, Were ou Had) para a frente de tudo.Ei! Isto é uma frase condicional, mas eu sou elegante!.
if e mesmo assim trocares as palavras, as pessoas vão olhar para ti de forma estranha, como se estivesses a usar os sapatos nos pés errados. Lembra-te sempre: Sem if quando trocas a ordem! Se estiveres a enviar uma mensagem a um motorista da Uber e quiseres ser muito educado, podes dizer Should you arrive early... em vez de If you arrive early..How This Grammar Works
Should, Were e Had. Cada uma tem um trabalho diferente. Pensa nelas como diferentes níveis de um jogo.Should é para o nível do Talvez. É para coisas que podem acontecer no futuro. Should you need help... significa que talvez precises de ajuda.Were é para o nível do Sonho.Were I rich, I would buy a private jet. (Eu não sou rico, infelizmente). É ótimo para falar sobre os teus sonhos da lotaria.Had é para o nível do Arrependimento. Isto é para coisas no passado que queremos mudar. Had I studied, I would have passed..Had I edited that better, it would have gone viral.. Cada palavra ajuda-te a expressar um sentimento diferente.
Formation Pattern
Should (futuro/possível):
Should.
you, he, the team).
s, sem ed).
Should you arrive... (em vez de If you should arrive).
Were (hipotético/imaginário):
Were.
I, you, she).
to + verbo.
Were I you... ou Were she to go... (em vez de If I were you).
Had (passado/arrependimento):
Had.
gone ou seen).
Had we known... (em vez de If we had known).
Pattern Variations
não? Para frases negativas, colocamos not depois do sujeito. Nunca digas Shouldn't you... no início destas frases; isso é para perguntas!Should you not..., Were I not... ou Had they not.... Soa muito sério, como um aviso num videojogo antes de um grande boss. Should you not follow the rules, you will lose..Were com um verbo normal; usamos a forma com to. Were they to buy the house.... Isto é apenas uma forma extra elegante de dizer If they bought.ultra-HD no teu vídeo do YouTube; nem sempre precisas dela, mas fica fantástico quando a usas! Algumas pessoas também usam were com substantivos: Were I the manager.... Isto é perfeito para quando te estás a queixar da interface de uma app: Se eu fosse o designer, faria estes botões maiores!.
Real Conversations
Locutor A: Should you have any issues with the Zoom link, please message me.
Locutor B: Thank you! Had I not checked my email, I would have missed it.
Locutor A: Were I to win the giveaway, I would share it with you.
Locutor B: That is so kind! Should that happen, I will buy you lunch.
Locutor A: Had the train been on time, we would be at the concert now.
Locutor B: I know. Were we not stuck here, I would be dancing!
Common Mistakes
if. As pessoas dizem frequentemente If should you need help... NÃO! Isso é como dizer Olá oi!. Escolhe um ou outro. Outro erro é usar was em vez de were. Em inglês informal, as pessoas dizem If I was you. Mas para a troca elegante, usamos SEMPRE Were. Were I you... é a única forma. Se disseres Was I you, parece que estás confundido sobre a tua própria identidade! Também tem cuidado com Should. Lembra-te de usar o verbo base; não digas Should he goes, deve ser Should he go. É como se o verbo perdesse o seu s quando vê o Should. Finalmente, não uses estes padrões em todas as frases. Se falares assim o tempo todo, vais parecer um robô de um filme de ficção científica dos anos 50. Guarda-os para momentos especiais! Usa-os na tua carta de apresentação para um emprego, ou numa mensagem educada para um vendedor no eBay. É uma ferramenta na tua caixa de ferramentas, não a única. Usa-a com sabedoria, jovem Padawan.Quick FAQ

No. In formal inverted conditionals, only `Were` is acceptable, even for singular subjects like 'I' or 'He'.
Mostly, yes. However, you will hear `Should you...` in formal spoken contexts like business meetings or announcements.
No. In inverted conditionals, you must keep the negative particle separate: `Had I not`. `Hadn't I` is for questions.
No, the meaning is identical to an 'if' sentence. Only the tone and level of formality change.
Never. You must choose either `If I had known` or `Had I known`. Using both is a major error.
This is used for Type 2 action verbs. Instead of 'If he asked', you say `Were he to ask`.
Yes, it is used in both American and British English, primarily in formal and academic writing.
Yes, it sounds less like a demand and more like a helpful suggestion in business contexts.
