Why use a bunch of words when just one (or two) will do the proverbial trick?
Here are some substitutions you can use to be less verbose:
As to whether => whether
Whether or not => whether
Due to the fact that => because
In order to => to
For the purpose of => to
In reference to => about
Subsequent to => after
Takes into account => accounts for
When your writing is wordy, long-winded and loquacious, your document will take too much time for your reader to read – and for you to write! Being concise will increase productivity all around.
