Introdução

Inversão envolve mudar a posição do sujeito e do verbo auxiliar ou modal.

Nós usamos inversão:

• Quando começamos uma frase com uma expressão adverbial negativa, uma expressão adverbial de lugar, ou simplesmente um advérbio
• Com: "only after", "only if", "only when", etc. colocados no início de uma frase para efeito retórico
• em frases condicionais sem "if"
• Para dar ênfase, geralmente parecendo mais formal.

Exemplos

• "Under no circumstances should you open the box."
  (You should not open the box.)
   
• "On the table were three old books."
  (Three old books were on the table.)
   
• "Hardly had I entered the room when the orchestra began to play."
  (I had hardly entered the room when the orchestra began to play.)
   
• "Only when it started raining did he give me the umbrella."*
  (He gave me the umbrella only when it started raining.)
   

* Observe que a inversão ocorre na cláusula principal, depois de expressões como only after, only if, only when.

Outros exemplos

• "Had I gone to university, I might have been a doctor."
  (If I had gone to university, I might have been a doctor.)
   
• "Had I not gone to university, I wouldn’t have been a doctor."
  (If I hadn’t gone to university, I wouldn’t have been a doctor.)
   
• "Had you gone to university, would you have been a doctor?"
  (If you had gone to university, would you have been a doctor?)
