Introduction
Ferengi is the language of the Ferengi species in Star Trek. The Ferengi are a capitalist alien species introduced in Star Trek: The Next Generation (1987-1994), created by Gene Roddenberry and developed by writers including Ira Steven Behr. Deep Space Nine (1993-1999) developed Ferengi culture extensively through the character Quark, played by Armin Shimerman. The Ferengi are governed by the Rules of Acquisition, a set of 285 rules written by Grand Nagus Gint. Type a message above and the tool looks up each English word in a Ferengi vocabulary dictionary.

How this tool works
The translator splits your input into tokens using a regex that separates letter sequences from non-letter characters. Each word token is lowercased and looked up in a dictionary. Multi-word phrases like "Grand Nagus" and "ship captain" are matched first (longest match), then single words. In English-to-Ferengi mode, the dictionary maps English words like "currency" to "latinum" and "boss" to "Nagus". In Ferengi-to-English mode, the reverse lookup runs. Words not found in the dictionary pass through unchanged. Non-word tokens are preserved exactly. The mode setting syncs to a URL query parameter. The Rules of Acquisition list is searchable by rule number or text content.
How the Ferengi language and Rules of Acquisition work
The Ferengi were introduced in Star Trek: The Next Generation (1987-1994), created by Gene Roddenberry. According to the Wikipedia article on the Ferengi, the species was developed by writers including Ira Steven Behr. Deep Space Nine (1993-1999) developed Ferengi culture extensively, particularly through the character Quark, played by Armin Shimerman.
The Ferengi are governed by the Rules of Acquisition, a set of 285 rules written by Grand Nagus Gint. The Rules of Acquisition are the most well-known Ferengi linguistic artifact. Ira Steven Behr wrote the rules for Deep Space Nine. The first rule, "Once you have their money, you never give it back," sets the tone for Ferengi business philosophy. Other notable rules include Rule 9 ("Opportunity plus instinct equals profit") and Rule 34 ("War is good for business").
The Ferengi language itself is not a fully constructed language like Klingon. According to Memory Alpha, the Star Trek wiki, Ferengi has a limited vocabulary of attested words from the shows. Terms like "latinum" (the Ferengi currency), "dabo" (a gambling game), and "oo-mox" (ear stimulation) appear in dialogue but do not form a coherent grammar system.
Star Trek: Strange New Worlds Season 4 premiered July 23, 2026 on Paramount+. Season 5 (the final season, 6 episodes) was filmed and is expected in 2027, introducing Thomas Jane as Dr. McCoy and Kai Murakami as Sulu. Star Trek: Section 31 (2025) starred Michelle Yeoh. Starfleet Academy ended after 2 seasons.

Real-world examples
Translating a business term
A user types "currency" in English-to-Ferengi mode. The tool looks up "currency" and finds "latinum". The output reads "latinum". They type "boss" and get "Nagus". They type "ship captain" and the multi-word phrase matcher returns "DaiMon". The user copies the output and uses it in a Star Trek roleplay scenario set on Deep Space Nine.
Browsing the Rules of Acquisition
Someone writing a Ferengi-themed story wants to reference Rule 9. They open the settings panel and type "9" in the rules search box. The list filters to show Rule 9: "Opportunity plus instinct equals profit." They type "profit" and see all rules mentioning that word, including Rule 22 ("A wise man can hear profit in the wind") and Rule 57 ("Good customers are as rare as latinum. Treasure them.").
Decoding Ferengi dialogue
A fan has a line of Ferengi dialogue from a Deep Space Nine transcript: "latinum". They paste it into Ferengi-to-English mode. The tool looks up "latinum" and finds "currency". The output reads "currency". Words not in the dictionary, such as character names or untranslated phrases, pass through unchanged so the reader can identify them manually.

Limitations or considerations
This tool performs word-level dictionary lookup, not full grammatical translation. The Ferengi language is not a fully constructed language like Klingon. It has a limited vocabulary of attested words from the shows. The dictionary covers roughly 10 terms. Words outside the dictionary pass through unchanged. The Rules of Acquisition list includes 22 attested rules out of the canonical 285. This is not encryption. For actual encryption, use the AES block cipher. For other fictional language tools, try the Klingon translator, the Aurebesh translator, the Huttese translator, or the Standard Galactic Alphabet translator.
