Mr N

Like a lot of other I.T. professionals I’m dyslexic and as a result I find it difficult to remember spellings and lists or groups of ordered items. What good is trying to remember SOHCAHTOA if you can’t remember how to spell it! So I would like to use this article to document all the Mnemonic Acronyms.

I’m describing a rhyme or saying where the first letter of each word in the rhyme or saying is a memory trigger to help you remember another word. English is big and I’m sure there is a particular word which describes what these are but I don’t know what it is, does any one know?

So here is my current list. Please add more to the comments and I’ll incorporate them into the article.
