Wlihe hmuans drevie ipmpilcit udnretsnadnig lragely from the 
smenatcis of snentcee srtcutrues, mchaines, pratciuclarly smiple 
lxeers, are rsetirtced to rcegoniznig, but not udnretsnadnig, srtcutrue.

Yes, in a snese, it is all smenatcis.  But, in the snese of use in 
froaml cmoptuer sceicne dsicuorse, to euqtae 'c' 'a' 't' to "cat" is 
srtutcrue, to euqtae 'c' 'a' 't' to "feline" is smenatcis.
