One of the books I like to keep next to my desk is Strunk & White's classic "The Elements of Style". It really is as good as everyone says it is, and well worth returning to whenever you suspect that your writing style is getting muddy.
My most pernicious lapse is probably "the fact that", which Strunk includes in a list of unnecessary words and their conciser alternatives, such as:
used for fuel purposes........ used for fuel he is a man who................. he in a hasty manner............... hastily this is a subject that........... this subject Her story is a strange one.... Her story is strange.
The little book is absolutely crammed with similar pieces of terse wisdom. Business writers are renowned for their unwillingness to get to the point, and their use of ridiculous, pompous, buzzwords. White's description is telling:
People in business say that toner cartridges are in short supply, that they have updated the next shipment of these cartridges, and that they will finalize their recommendations at the next meeting of the board. They are speaking a language familiar and dear to them. Its portentous nouns and verbs invest ordinary events with high adventure; exectives walk among toner cartridges, caparisoned like knights.... A good many of the special words of business seem designed more to express the user's dreams than to express a precise meaning.
I'm on board with that.
