Ido Dictionaries

(based on the dictionaries by L.H. Dyer, updated, expanded, and corrected 2016)

Great thanks to Mr. David Mann for heading the project of transcribing the original Dyer Dictionaries to html, and for his generous help during this project. I have updated these pages with current usage (i.e., "patro" instead of "patrulo"), all officially adopted words and have inserted all words from the Radikaro of Pesch, as well as many proposed words (marked with an asterisk) that seem necessary for modern communication. I have also corrected typographical errors and standardized punctuation and formatting, to create the most complete, most accurate Ido-English dictionary within my power. My intent is not to offer a transciption of the Dyer Dictionaries, but to create a modern, practical dictionary for English-speaking Idists. I hope that my efforts will make this great project even more beneficial for all Idists. If further errors are found, please email me.
