Eliminate redundancies
Tighten wordy sentences
Clarity
Long sentences are not necessarily wordy, nor are short sentences always concise. A sentence is wordy if it can be tightened without loss of meaning.
16a Eliminate redundancies.
Redundancies such as cooperate together, yellow in color, or basic essentials are a common source of wordiness. There is no need to say the same thing twice.
Though modifiers ordinarily add meaning to the words they modify, they are redundant when their meanings are suggested by other words in the sentence.
