Questions & Answers about Rivelinte la foton, ŝi kontrolas la kontraston.

What does Rivelinte mean, and how is it built?

Rivelinte is an adverbial active past participle.

It is formed like this:

• rivel- = the verb root
• -int- = active participle for an action completed earlier
• -e = adverb ending

So rivelinte means something like having revealed / having developed.

In this sentence, it shows that this action happened before the main verb:

• Rivelinte la foton, ŝi kontrolas la kontraston.
• Having developed the photo, she checks the contrast.

Why does Rivelinte end in -e instead of -a?

Because it is being used adverbially, not adjectivally.

• -a participles describe a noun: rivelinta virino = a woman who has revealed/developed
• -e participles describe the action of the clause: rivelinte = having revealed/developed

Here, rivelinte la foton does not directly describe ŝi as an adjective would. Instead, it gives the circumstance of the main action: after doing X, she does Y.

Who is understood to have developed the photo?
