This dictionary is organized in sets of proverbs, where the English proverb is followed by one or more Portuguese equivalent proverbs. The English proverbs are arranged according to a main word; equivalent proverbs are those which express the same concept, be it literally or with different words.

Proverbs included in this collection come from monolingual, bilingual, and multilingual collections, some as old as the 16th century, and it should be accepted that some of them are contradictory, discriminatory, blasphemous, or scurrilous, and as such, they reflect past attitudes and express the idiosyncrasies of a people and their culture through time and history. At the same time, proverbs are based on the practical experience of humankind and show us that we can change and do better.

While proverbs are still used today in a traditional way, that is in speech, literature, and teaching, they have found a new ever-expanding use in the advertising industry and in the mass media. Proverbs like "Here today, gone tomorrow" become "Hair today, gone tomorrow" in the hair-removal industry, while the mass media has a variety of paraphrases such as "Hear today, gone tomorrow" and "Heir today, gone tomorrow". Before the Barcelona Olympic Games, the old proverb "All roads lead to Rome" became "All roads lead to Barcelona" in many English language newspapers and magazines. This is a phenomenon encountered in many languages today and is undoubtedly a sign of the proverb's resilience and vitality.
