Replace "basically" with nothing.
This word never adds value. It is usually a manifestation of the author's or speaker's unconscious concern that what he is explaining is too complex. If time allows, revise the material until your readers don't need extra convincing that it is basic. At least get rid of the useless word.
You could have some fun writing a regular expression to correct all instances with a global search-and-replace. If you're amused by the challenge, please feel free to post your regex in the comments. You'd be helping all of us.
Here are the replacements your regex would need to catch:
|Basically, it can start a sentence.||It can start a sentence.|
|Basically people leave off the comma, too.||People leave off the comma, too.|
|It can basically appear in the middle.||It can appear in the middle.|
|It can, basically, be set off with commas.||It can be set off with commas.|
|It can end a sentence, basically.||It can end a sentence.|
|It might end without a comma basically.||It might end without a comma.|
Replace "essentially" with nothing.
Replace "is nothing more than" with "is."
The "is nothing more than" construction falls in the category of noisy hedge words. It's a large category. Folks add words to forestall arguments. Even though it sounds romantically brash—X is nothing but Y, #wristforehead—it actually weakens the association between the subject and its predicate nominative. Be clear; be bold. If you're trying to define X by saying that it is Y, say that X is Y.
I wish the industry allowed more time for editing. I wish I were able to help more people express their ideas. Good editing is liberating, plucking the brambles and cruft off a passage until its central theme floats to the fore—getting the text out of the way of the writing.
I hope you find these tips helpful and easy to implement. Ruthlessly delete useless clutter like "basically," "essentially," and "nothing more than." Let your ideas stand tall.
