Methods of rephrasing a sentence include removing passive voice, removing gender ambiguity, removing or altering modifier phrases, and eliminating redundancy. Performing all of these steps as necessary can make a passage easier to read without sacrificing critical content.
Two types of voice exist in sentence structure: active and passive voice. Active voice has the subject performing an action on the object. Passive voice reverses the sentence structure with the object coming first. Most writing benefits from primarily using active voice. As a humorous mnemonic device, if you can add the phrase "by zombies" to the end of a sentence while keeping it grammatically correct, it is passive voice.
To address gender ambiguity, pick the gender of a subject and stick with it throughout the passage. Avoid using "he or she" because this is wordy. Only use "it" for animals or inanimate objects.
Misplaced modifiers consist of adjectives and adverbs that are not placed next to the noun or verb they should modify. Think about the intended meaning of the sentence; place modifying words or phrases next to their intended subjects.
Redundancy or wordiness can also harm writing. Choose "right now" or "at this time" instead of "at this point in time. Instead of "henceforth going forward," write "from now on" or "going forward." Cut the phrase "estimated roughly" down to "estimated."
