"Lui l'ha dimostrato."

Translation: He has demonstrated it.

[David1945]

Does dimostrato agree with the object rather than the subject of the sentence, otherwise 'He has shown her - should be acceptable?

[f.formica]

Yes, when using a clitic with the auxiliary avere the past participle can agree with the object, and it's mandatory with l' to differentiate between "lo" and "la".

[David1945]

Thank you!

[lacrimae2]

But in this case it is" Lui l'ha dimostrata", I think

[ZuMako8_Momo]

It depends on what «l'» stands for. If «l'» stands for «la presentazione», then it would be «Lui l'ha dimostrata.». If «l'» stands for «il rapporto», then it would be «Lui l'ha dimostrato.».

[cosifantute]

Shouldn't be OK "He has proven it"? Thanks in advance.

See my comment here: https://www.duolingo.com/comment/1019808 :)

[PATRICKPIZ1]

this comment, although correct, does not apply to this particular sentence. 'prove' is definitely a correct answer here.

[AnneAho]

I was wondering the same thing. Does anybody have an answer / explanation?

[Sylvia754597]

Was marked wrong for using prove. But I think that it should be correct.

[ICeRqrWG]

What about translating "dimostrato" with "proved". (He proved it.)?

[scimmia0]

The system never accepts my spoken items so I recorded it and played it back. It still did not accept!

[BronzetheSling]

So how would you say 'Show yourself'?

[ZuMako8_Momo]

Perhaps «Mostrati.». I think of «mostrare» as "to show" and «dimostrare» as "to demonstrate."

[Tommaso27gz]

Duo would not accept: He "proved" it. Dimostrare can also mean: prove, demonstrate, or show

[Hayden_Italian]

"He has demonstrated it." Feels inaccurate on the basis of being archaic. Nowadays we say 'He has shown X even in highly academic settings. I feel that there should be a range of new meanings included to match the purpose of the phrase rather than it's now outdated 'direct' translation.

[MariannaLead]

I'm confused as to why its not He showed her.
