In my opinion there are two types of vocabulary in natural languages:
    1) basic vocabulary that is rather diversified: words are recognizable with some variations only in the limits of small families of languages.
    2) scientific, technical, medical, geographic, historic (etc.) vocabulary: words are recognizable with some variations in several very large families of languages.
    This second type of vocabulary is the most richest one and dropping hundreds of thousands of so international words would be inconsequent .
    I personally recommend a posteriori languages.
