Of COMPARISON.
Comparison is the comparing the different Circumstances of Persons or Things with each other, and serves to alter the Signification of a Word, either by a gradual Increase, or a gradual Diminution; as long longer longest, short shorter shortest.
Adjectives, Adverbs, and Substantives, have three Degrees of Comparison, the Positive, the Comparative, and the Superlative.
The Positive lays down the Natural Signification simply and without excess or Diminution; as long, short, often.
