English is easy but a  tricky language, many times people end up in spelling errors.  There are many words which sound similar but have totally different meanings.  Change of even a single letter would be erroneous and end up in changing the meaning of the word and the whole sentence too.  Errors are common as we are all human and of course they make us laugh out loud.  To know the fact that the word misspell is one one of the top 100 misspelled words in English language is really hilarious...
