Resolve "Make tokens easier to write and copy"

I started out wanting to use real-world Dutch dictionaries for this generation. However, I quickly realised that the number of possibly insensitve words (death/murder/...) would be endless, and it would be far quicker to create our own dictionary with a set of innocent daily words.

Please let me know if you have any other suggestions for the dictionaries! Only condition is that the words are between 3 and 7 characters (inclusive).

Currently, this generates 6,468,000 possible tokens, which is a lot, but maybe not enough.

Here is an exemplary set of tokens being generated:
