This is by no means intended to be an exhaustive list. It simply lists misspelled words that I find particularly painful. The painful words are ones that are commonly used, and therefore theoretically easy to remember and naturally commonly misspelt. It is also an ongoing project and I add significant typos as I notice them. Please feel free to /msg me with words that could be appended to this list.

     Instructions for use (AA batteries not included): Commonly encountered misspelling of the word is followed by the correct version.The numbers below each entry refer to the google matches for each version of the word (misspelt version vs. correct version) and this section is intended to show that you are not the only culprit. When in doubt:

  1. Check the Battery status of your Guide
  2. Consult the guide.
  3. Replace misspelt word
  4. Click stumbit
  5. The Guide:

definately - definitely

The word definitely is related to the word finite. Recalling this should expel any doubts concerning the evil introduction of an 'a'.

humerous - humorous

The word humour/humor (depending on which side of the Atlantic you're on) is rarely misspelt so the infiltration of this particular horror baffles me no end.

There's no use having long lists of misspelled words without a way to get people to spell them right! This is a collection of tricky words, and ways to spell them correctly, that I've picked up over the years.

The methods listed here are all positive methods - they teach you how to spell words right. Negative methods teach you how not to spell a word wrong. It's a bad idea to try to learn both types at once, lest you get confused and learn the incorrect spellings by mistake.

This far from a complete list; the mnemonics mentioned here are just ones that I've been learning gradually. Many have different versions - necessary can have crisps/chips instead of cakes, for example. If you know any that I have missed, please /msg.

Still stuck?

If you're trying to remember a spelling, and can't remember any of the methods listed above, you could always...

  • Try writing the word down. Sometimes you can tell if it 'feels' wrong.
  • Try saying the word to yourself. "Mispell" sounds a bit like "My Spell", where "Misspell" sounds like it is said.
  • Knock off any endings. "Definately" gets shortened to "Definate", and that doesn't look right...
  • Knock off any beginnings. "Mispell" gets shortened to "Pell", and Miss Pell won't be too happy with that.
  • Use synonyms - if you know what a word means, try using a different one. "Housing" instead of "accommodation", "needed" instead of "necessary", "spelt wrong" instead of "misspelt", for examples.
