Google gives me "late Middle English: from Old French ethimologie, via Latin from Greek etumologia, from etumologos ‘student of etymology,’ from etumon, neuter singular of etumos ‘true.’". It doesn't give the fancy tree diagram though.

It won't do the word "computer" either, though it does do "compute".

Try again. That was fast.

I mean it does not display that nice graph.

Yes, I was under the impression the graph was the feature. The textual description of the etymology, I thought, was already often an included part of the snippet.

It works for me using Opera Next. Chrome, FireFox and IE: No go :)
