"¿Viste mi diccionario de italiano?"
Translation:Did you see my Italian dictionary?
23/07/2018 "have you seen my italian dictionary?" marked wrong. This is not the only case where DL uses "Did" which does not work with the past tense verb conjugation, when "Have" which does work with the past tense verb conjugation, should be the right tool for the job.
I also think that "Have you seen my Italian dictionary" is a valid translation here.
I typed the same thing and it was marked incorrect. Reported it 8/5/2018
Doesn't matter, I still can't find my Italian dictionary and I would not know a preterit if I stepped on one.
