I've got the answer already!
Found the dictionaries.pisi and the help.pisi I believe on the Pardus FTP, downloaded, put them on the USB stick, moved them to the desktop in Pardus, installed manually via the terminal, both works like a charm!
OpenOffice language packs are also compatible with Thunderbird and Firefox, and can be used to add dictionary support for languages not otherwise supported by Mozilla.
The relevant spelling dictionary can be downloaded from http://wiki.services.openoffice.org/wiki/Dictionaries
, unzipped, and the .aff and .dic files copied to /usr/lib/MozillaThunderbird/components/myspell/ or usr/lib/MozillaFirefox/dictionaries/
