Ficbot Hi, here is a way to try and set your standalone French dictionary as a lookup.
Doitsu a formum member supplied this info to me, all credit to him.
The Kindle software versions for PCs and smartphones only support the default 7 monolingual dictionaries. (English US/UK, French, German, Italian, Spanish and Portuguese)
The only way to bypass this limitation is to change the ASIN number of the dictionary that you want to use instead.
(The ASIN number for the default French dictionary is *B005F12G6U*.)
If you want to use your French-English dictionary with K4PC, create a copy of your dictionary, add or change the ASIN to *B005F12G6U* and replace the default French dictionary in the My Kindle Content folder with your patched version.
IMHO, the easiest way to change this ASIN is to use the Mobiperl command line tools (
https://dev.mobileread.com/dist/tompe/mobiperl/) with the Mobi2Mobi GUI (
https://www.mobileread.com/forums/showthread.php?t=21763). (The ASIN is eth type #113.)
I tried this for Kinldle for PC and it works so if you remove the standard French dictionary from your kindle, then use the tools Doitsu suggests (on a PC to alter your French to English dictionary's ASIN number to *B005F12G6U* then load it onto kindle it should directly lookup your one. Let me know if it works
