[tshering]

I would like to mention that the performance of the English definitions dictionary (and presumably also of other dictionaries) could easily be improved by making better use of the variants that are recorded in the dictionary. Currently, variants seem not to be taken into consideration, when they are available only in abbreviated form, like "-aries" in the case of "boundary". To check this, I went through the dictionary and resolved the abbreviated variants. I add some images for illustration.
I resolved a little more than 7500 abbreviated variants. The advantage, however, is less than this number might suggest, since a lot of cases are covered by a kind of automatic matching, which seems successful in cases like radiate : radiated.
