Alternatively, you can take a 48000-word English dictionary, preferably one of the same brand as your French one, sample count how many English words you know there, say 30 out of 39, and assume your French vocabulary is 15/30 of your English vocabulary. (The 15 from 15/39).
I don't think that is mathematically valid. Since the two ratios would be completely different.
However, as promised I did the same exercise with the same French dictionary but with more samples. This time I used the other "corner" words on the pages. After an additional 150 samples plus the previous results I'm now showing a vocabulary of 17,073 words. I'm thinking that if I continued with the dictionary I would probably begin to centre somewhere around the 15k mark. Obviously this is just a guess, but there wasn't much change from the larger sampling than my previous one of 18,461. This is a change of only 7.52%. I'm going to call time on this method but I'll try to do a word count from a frequency list and do the maths that way.
