As I was documenting something as innoculous today, I thought I better double-check my spelling. Google works well as a spell-checker, either giving you a definition link or suggesting the correct spelling if it’s not a word. For once, Google was at a loss for words. It offered neither definition nor correction but just links to 590 pages using the word. 590 links is a pretty good sign a word is misspelled, and badly misspelled at that; by comparison, incredable gets over 150,000 hits (and a suggestion with the correct spelling).
Next I tried the dictionary widget that comes with OS X 10.4. No luck there after trying several possible alternatives. Unlike a real dictionary, I was unable to browse for words that started with, say, inno which would help me out in case of any unsuspected silent letters. Noticing the widget also had a thesaurus (32,000 Google hits for thesauras), I looked up synonyms for harmless and immediately found innocuous. Of course!
Later I tried my email app’s spell-checker on innoculous and it did figure out what I meant.
