duome.com, FAQ: It's a little bit unclear actually: there are 2151 lexemes in Spanish Tree v2.0 which equals to 1603 words in your "personal vocabulary", even though the words tab lists 2900+ words... I would expect the smaller number to be called "lexemes" while the larger number would stand for "words", but we have three different numbers here
