It is amazing to know how well we usually read the words. I guess most times we just make the word ourselves looking at it and not reading it. There was also a study sometime back that we usually follow the sentence or guess the sentence before reading it most of the time and proceed irrespective of how common words are spelled.
Few minutes ago, I was AMAZED for a moment when Word application didn’t recognize the word – VACCUM. What do you call and how do you spell a volume of an empty space of matter? For many years I always spelled it as v-a-c-c-u-m (vaccum cleaner, for instance); only now that I noticed it spelled as v-a-c-u-u-m. I just noticed even Wikipedia re-directs me va-c-u-u-m when I searched for va-c-c-u-m.
Oh, even Technorati has tags spelled in both ways – vacuum cleaner and vaccum cleaner.
I tried on Miriam webster – it suggests possible spellings
I looked for a vaccum cleaner on Best Buy store website; although it lists what I am looking for but they are spelled as vacuum cleaner.
Are they both correct and differ in different regions?
