Hello everyone,

can someone tell me where lyx stores the personal dictionary ?

I'm performing a new debian install and would like to get my dictionary 
back from the previous one.

Thanks,

regards,

Denis

PS : this is with lyx 2.1.2 on a Linux Debian Jessie system, using 
enchant / hunspell as dictionary manager
