Neolatin and contemporary Latin dictionary

Question

What are some good, reliable English–Latin dictionary of Neolatin and contemporary Latin.

The best one I've found so far is Morgan's Lexcon of Neo-Latin and Contemporary Latin Usage on the Paideia Institute website, but I do not know the difference between the Silva and the Adumbratio. There is also the Lexicon Recentis Latinitas from the Vatican. There is the online excerpt here, and I know there is a book. The excerpt is, however, Latin–Italian, and I do not know Italian. Although I could ctrl+f search the online excerpt, I do not know if there is a vernacular–Latin section of the book. There is Vicipaedia, Latin Wikipedia – which, although having many useful terms, does not contain everything one might want to translate. Cassell Latin Dictionary has a good English–Latin section with some New Latin vocabulary, but I do not believe there are many modern words. The Bantam New College Latin & English Dictionary by Traupman has an English–Latin section that seems to have many modern words. Similarly, Traupuman's Conversational Latin has what seems to be a quite comprehensive English–Latin general vocabulary and an appendix containing computer terms. It does not, however, give sources, and I have heard that some of the terms are Traupman's invention and others are taken from general usage.

Any guidance is appreciated.

Answer 1

• Adumbratio ("the draft") is certainly the go-to dictionary of modern Latin, and besides offers a lot of generally useful timeless vocabulary. It's very well-researched, draws on most of the sources you may want to consult and usefully provides extended quotations. The project is being maintained and developed, with a focus on creating a better (than no) interface. There have been several mirrors over the years, but the developed version is neolatinlexicon.org. Unlike the one at Paideia, the search isn't full-text but by lemma; however this is still in development. To use full-text search, open the plaintext "old" page and ctrl+F.
• Silva ("the forest > source material collection") is not a dictionary in the same sense, being rather a translation notepad where you can find ideas for rendering words that didn't pass the muster to make it into Adumbratio, but also many neologisms and importations of very questionable Latinity (cf. the preface). It's not being updated, and its use obviously requires a fluent speaker's judgement.
• Here's a short history of the project up to 2017 by its current editor-in-chief, Patrick Owens.

Answer 2

Probably not exactly what you are looking for, but maybe interesting in general: A very good German - Latin (hardcover-)book, entitled "Lexicon Auxiliare", was issued (as 3rd edition) in 1991. Christian Helfer was named as the (main) author. Its purpose was to list only words that are too rarely used for common lexica, including a lot of neo-Latin words.

Answer 3

Alternative options:

• Latinitas Recens (Speculum) and by letter by Numen, The Latin Lexicon, is another plaintext collection which draws on a decent number of sources (which it cites) but doesn't overload the user with the number of suggestions.
• Lexicon Recentioris Latinitatis by Blasius Amata - gloriously cloned from GeoCities. Has fun stuff like 1001 Computer Words with equivalents in English and Italian by Anthony Stanley, as well as some Christian terminology and abreviations.
• Glosbe.com is a translation equivalence database that can be surprisingly useful even for Latin provided the user pays attention to the translation's source and can spot all the made-up and vicipaedic Latin (this caveat also applies to the other languages they offer).

Answer 4

• Diccionario auxiliar Español-Latino para el uso moderno del Latín, mirror by José Juan Del Col is what I use when I don't use Adumbratio. Handy and comprehensive, despite the lack of sources or quotations, and only occasional collocations. The latter fact places the job of quality control entirely on the user, so I would only recommend it to fluent Latinists. Doesn't require much proficiency in Spanish.
• Vivae Latinitatis Voces Locutionesque, by the same author, is a collection of modern Latin vocabulary from Vatican sources, translated likewise into Spanish.
