The sentences that appear in the Examples section on dictionary and translation pages, as well as the examples for individual verb conjugations, do include sentences from our dictionary that were written by our team. However, the vast majority of the more than 20 million sentences that are in the Examples database come from a variety of online corpora that include movie and TV subtitles, court and governmental records, and free books. We have not read through all of those sentences. This is why we show a disclaimer at the top of each Examples section that says the sentences have not been reviewed.
We include these examples on SpanishDictionary.com to give people access to a much larger body of information than our team could write by themselves. The sentences do not necessarily represent certain language characteristics like the frequency of use of a particular definition or translation of a word.
