I recently heard about Word Hippo, from a school pupil at Victoria Park Academy in the West Midlands, England. It’s an online dictionary, thesaurus and general all-round word helper.
I’m used to using the Oxford English dictionary and similar reference works, to which I have access through my library membership, so I wasn't feeling tremendously optimistic when I approached Word Hippo.
However, as you can see from the screenshots below, the range of options is impressive. I tried out “granularity”, just to put it through its paces. It wasn’t able to come up with a sentences containing it, or a word which rhymes with it. It came up with a definition and a synonym, but not its antonym.
That’s a bit odd, when you consider that it came up with “coarseness” as a synonym: you wouldn’t have thought it would be that difficult to produce something like “fineness”.
Still, as a general all-purpose online dictionary it’s hard to beat. It’s free as well, which is always nice!
