I just wanted to drop a note to everyone about the Greek Phrase book Sprechen Sie Attisch: Moderne Konversation in altgriechischer Umgansprache nach den besten attischen Autoren. By E. Joannides (Eduard Johnson). 2nd Edition, Dresden und Leipzig, 1902. Publisher: C.A. KochsVerlagsbuchhandlung (H. Ehlers). It is available for download as a pdf from Google Books or Internet Archive.
This book is a treasure trove of phrases for everyday situations. Some of the phrases may need to be compared to find if they exist in authors (the writer says they are extracted from the best Attic authors). Also, the Phrasebook is Attic, so the later Koine might be a little different.
The German is currently being translated into Greek by several people. What currently exists can be found at http://www.letsreadgreek.com/phrasebook/
. This is a collaborative effort to get it into the public Domain. Some excellent scholars and adequate co-conspirators are getting this together. But there is room for people to still translate some blocks of pages, vet the German translation (Do you know German?) and make comments on whether the phrase is only Attic. If the phrase would be different in Koine, there is a column to hold that text also.
Only pages 20-43 are translated as of now. There are typos and translation ambiguites, etc. So if you can help vet, translate, type the Greek list of words or make the page appear better (The data is being stored in an Excel file), please send me a note.
Thanks for your help and enjoy!
