Learn Dutch: Wij hebben gisteren dezelfde versie als jij gedownload. - We downloaded the same version as you yesterday.

The word you use depends on the gender of the noun. Because versie is a de-word (de versie), we use dezelfde. If you were talking about a het-word, like het programma, you would use hetzelfde (hetzelfde programma).

Why is the pronoun jij used after als instead of the object pronoun jou?

In Dutch comparisons, you have to look at the role the pronoun plays in the implied rest of the sentence. Here, you are comparing what we downloaded to what you downloaded. Because you are the subject of the implied action (als jij hebt gedownload), you must use the subject pronoun jij. Using jou is a common mistake among native English speakers translating literally.

In English we say 'downloaded the same version', so why is gedownload at the end of the sentence here?

This sentence uses the present perfect tense (hebben ... gedownload). In a standard Dutch main clause, the conjugated verb (hebben) takes the second position, while the past participle (gedownload) is pushed to the very end. It forms a verb bracket around the rest of the information (gisteren dezelfde versie als jij).

How does the past participle gedownload get its spelling?
