How and where from do I download a dictionary with meanings for my word game?

I want to essentially get a list of 4 and 5 letter English words with no repeating letters and their meanings so I can export it and use it in my game

github.com/dwyl/english-words

raw.githubusercontent.com/sujithps/Dictionary/master/Oxford%20English%20Dictionary.txt

Getting the meanings too will be a tall order. Keep googling and you may find one, but a quick look on my part didn't yield anything.

You'll have to probably make such a list yourself. Doing it manually would be the least ideal. Another would be to scape what you need from a website like this:

vocabulary.com/lists/52473

With some work you can take that and has a bunch of words and definitions. Maybe if you're clever you can find a way to automate it.

Another idea is to get an electronic version of a dictionary and scrape the info you need out of that, but that's more rough with copyright considerations. Seems like a lot of busy work either way.
