|Degrees of adjective and adverbs (modifiers)|
|eager||more eager||most eager|
|efficient||more efficient||most efficient|
There are a number of other unacceptable forms as well as problems with comparisons.
Double comparisons occur when the degree of the modifier is changed incorrectly by adding both -er and more or -est and most.
The misuse of the superlative occurs when a comparison is made between two things or people and the superlative form is used incorrectly.
The superlative is also used incorrectly when it is combined with any other, meaning only one or with all the others, thereby excluding the compared item from its category. For example, the sentence below suggests that Montreal is the largest of one city.
Illogical comparisons occur when there is an implied comparison between two things that are not actually being compared or that cannot logically be compared.
Ambiguous comparisons occur when elliptical words (those omitted) create for the reader more than one interpretation of the sentence.
Incomplete comparisons occur when the basis of the comparison (the two categories being compared) is not explicitly stated.
Omission of other, any, and else: Do not omit the words other, any, or else when comparing one thing or person with a group of which it/he is a part.
If the superlative is intended, use the following: Joan is the best writer in her class.
Omission of as: Do not omit as when making a point of equal or superior comparison-as. . .as.
Further, in such comparisons as the following, all one need do is omit the italicized phrase to see why the comparison is faulty.
