Estimate the Size of your Vocabulary!

(new improved version with a better word sample: less proper nouns, Latin words and so on.)

    This is essentially just a statistical tool. The Calculator contains a sample of over 16000 words and phrases, drawn originally from a list of eight times that number.

    You have to assess a reduced sample (a minimum of a hundred words) which should take about five minutes. Continue beyond this to improve the validity of the estimate.

[Read more about the vocabulary calculator (how to use it, how reliable it is, how it works etc.) here.

Also, you can download the original word list (with 132208 entries) as a zipped Excel spreadsheet here. It could be useful for all sorts of things!]

     Results can be obtained for three categories:

A - Understood - Words you fully know and understand.

B- Inferred - Words of which you can deduce the meaning, despite having never heard them.

C - Familiar - Words that you remember hearing, but cannot define yourself.

(Of course, there is nothing whatsoever to stop you from defining the categories differently.) Off you go then!
