Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
In case you couldn't read that it says: According to a research at Cambridge University, it doesn't matter what order the letters in a word are, the only important thing is that the first and last letter be at the right place. The rest can be a total mess and you can still read it without problem. This is because the human mind does not read every letter by itself, but the word as a whole. To prove this, I had about 12 students at AMS read the statement. They ended up all being able to read it.
However it won’t always work. For example, if you had a word like photograph, where the ph makes the f sound, it would be harder to read: pohoatgprh. That wasn’t as easy to read as the word hppay, was it?
