When I try to use DictionaryWordQ["word"] I get a list of errors:
Get: Cannot open SpellingData`.
Needs: Context SpellingData` was not created when Needs was evaluated.
Keys: The argument SpellingData`SpellingDataDicts is not a valid Association or a list of rules.
DictionaryWordQ: Spelling dictionaries for English are not available.
I assume that no dictionary comes with Mathematica distribution on Raspbian
How can install a dictionary? Or there is some other problem?
