Lexipedia is a new online dictionary that has taken a visual approach to the whole premise. That is, whenever you key in a word you are presented with related words in a graphical manner, reminiscent of a grid that highlights connections.
This includes verbs, adverbs, synonyms and antonyms along with something I was frankly not familiar with named “fuzzynyms”. These seem to be words with a fuzzy semantic relation.
As it is only appropriate for a linguistic resource, this site is available in several languages. In addition to English, Spanish, French and Italian are all accounted for, and the same goes for German and Dutch.
By way of conclusion, the site offers a service that will mainly appeal to those who are looking into having a better representation of the relations between words. That is, linguists and related language professionals like translators and so forth. Still, casual users might derive some uses from it, but I don’t know if they will keep on coming back to the site after they have checked it once.
