A comparative sentence must clearly identify all the items that are being compared. This will help to ensure the comparison is complete. Complete comparative sentences also help to strengthen the delivery and clarification of the comparison. Below are some examples:
Incomplete Comparison: My car is newer than his.
Complete Comparison: My car is newer than his car.
Comparative sentences often use the words “more” and “most”. When the situation calls for the usage of these words, “than” and “that” must also be used.
Consider the following sentences:
Incomplete: My car is more new.
Complete: My car is more new than his car.
Consider it something that must be balanced. The concept is similar to solving a math equation; whatever is done to one side, must also be done to the other. In writing, any time the words “more” or “most” are being used, “than” and “that” must also be used.
