I'm looking for resources on most common general word lists for English. I'm after lists that are bit large in size - say in the range 10,000-20,000 words.
I have found smaller lists such as the GSL (2000) and the Oxford 3000.
There are also the frequency lists publish by Wikitionary:
But these are crude lists with no editing done to them to clean them up. For example they contain proper names, acronyms and different forms of the same word.
Can anyone here suggest online resources on lists of common words that are cleaner and within the mentioned size range, maybe a list of words in some beginners or learners dictionary?
The reason behind this question: I'm looking for a resource for learners where they can test their mastery of basic vocabulary. So what we're after is a list of most common general English words in the range given, preferably ordered by frequency, or ordered into groups like the most common 3k group then the next most common group and so on.
For the list to be useful it needs to have been cleaned up by human editing - so things like acronyms, place names, person names and affixes should not be included.
Learners can then go through a list of their chosen level, and if they find a word they're not familiar with they can check it in a learner's dictionary of their choice.
Note: I'm not inviting discussion on the validity of this as a learning technique.
