How to enliven dull writing

Three practical ways to transform bland into gripping.
Dull writing is wordy, passive, vague and listless. It has no rhythm, is hard to understand, and abuses language. Some of the culprits are easy to identify. To fix them is a matter of technique.
It may seem that a good writer has more talent than the rest of us, but like any skill, developing a good writing style is a matter of mastering specific techniques. You can transform any piece of dreary writing by identifying and eliminating three culprits of tedium: overused prepositions, lacklustre verbs, and meaningless nominalisations.
Slash the prepositions
There are about 150 prepositions in the English language. While they are essential to writing, their overuse results in wordiness and passive-voice sentences. Examples are above, against, by, of, with. Some prepositional phrases are at the beach, under the chair, on the bridge. Compound prepositional phrases are with respect to, in reference to, for the purposes of.
The following "before" examples are from real websites that offer writing services. The "after" examples demonstrate how the clutter produced by prepositions can be eliminated.

• Before: Our writers work in close proximity with the clients to understand their needs and then improvise their content as per these requirements.
  After: Our writers work closely with clients in order to understand their needs and write content that meets those needs.
• Before: We boast of writers who have great command over the language and can write for any given industry or sector.
  After: Our writers have a great command of the language and can write for any industry.

Power up those verbs
Verbs are action words. A powerful verb conveys feelings and stimulates the imagination. The best way to transform hollow verbs such as go, walk, come, run, think, know and get is to use a Thesaurus or dictionary of synonyms. You can even use the synonym finder in Microsoft Word. For example, type the word “walk”, right click on it, and select Synonyms to see the alternatives: saunter, stroll, amble, march, stride, pace, hike and toddle.
Ditch the nominalisation
A nominalisation is a verb that has been turned into an abstract noun, for example, movement, excitement, and failure. Because they are intangible and cannot be seen, touched, heard or tasted, nominalisations are excellent for creating fluffy, abstract writing that sounds important but is meaningless, serving no more than to bewilder the reader. The only way to gain movement and meaning is to turn the nominalisation back into a verb or adjective and make it a process.
Before: My reaction to the report was a negative one.
After: I reacted negatively to the report.
Before: The girl has not had the benefit of representation by counsel.
After: Counsel has not represented the girl.
Then there is the double nominalisation, a favourite of politicians, business and academia. It sounds impressive but is so open to interpretation that it overloads and numbs the mind. For example:

• Learning disability (who is not learning? how are they disabled?)
• Knowledge management (who knows what about what and how is it managed and by whom?)
• Informational relations (who is informing whom? who is relating?)

To conclude
Using these techniques will de-clutter your writing, add interest, and remove ambiguities.
