@BookCat - There is an English dictionary, but I cannot remember if initially you have to access the internet in order to download it or if comes already pre-installed (I thought it was already installed, though it is not that good).
However, if you follow this mobileread link

you will see a zip for a dictionary which works on the Touch HD 2. It is a composite of two open sources and is the one I use. You can download it to your pc/laptop and side load it to your Touch, you just then have to activate it within the Languages section of Settings.
