While we
have rigourously checked the content in this app for correctness, there is
always the risk of human error, and that a word has been misspelled, or an
alternative spelling has not been included. Either that, or the dictionary
you are using is not one of the ones which we have chosen as being the most
academically correct. Yes, there are discrepancies between dictionaries, and
the app only accepts spellings which we verify with our own sources.

If you
do find a word which is misspelled, please let us know, along with your
source against which you have double checked the spelling.
