WARNING: neither are entirely reliable. Word-count includes everything
with a space before and after, e.g. 4., which is not a Word .

not include art and design jargon, and it will not eliminate
mis-spellings that are other words e.g. world for Word .
Your essay should get a final proof-read by a human, preferably not
yourself; we are always better at spotting other people's mistakes.
