Questions & Answers about Ayer se confirmó que el nuevo cálculo lo habría demostrado.
Why do we use habría demostrado here instead of just the simple conditional demostraría?
The conditional perfect (habría demostrado) translates to 'would have proved.' It is formed using the conditional of haber (habría) plus a past participle (demostrado), and it's used for hypothetical situations in the past. If you used the simple conditional (demostraría), it would mean 'would prove' in the present or future.
Why is the pronoun lo placed before habría instead of being attached to the end of demostrado?
With compound tenses like the conditional perfect, object pronouns like lo must always go immediately before the conjugated form of haber. You can never attach a pronoun to a past participle. Therefore, lo habría demostrado is correct, and trying to say habría demostrádolo is grammatically incorrect.
Is there a missing 'if' clause in this sentence?
Very likely! The conditional perfect often relies on an implied past condition that wasn't met. For example, the full thought might be '...lo habría demostrado (si no hubieran perdido los datos)' (...would have proved it if they hadn't lost the data). Even without stating the 'if' condition, native speakers understand the hypothetical nature of the action.
