Gradable adjective and adverbs can also be involved in comparison where the positions of two or more entities on a gradable scale are compared with each other. Semantically, three types of comparison can be distinguished:
* higher degree (superior)
* same degree
* lower degree (inferior)
Comparisons of the same degree use only the general base adjective form.
In higher degree comparisons, the comparison is indicated either by inflectional suffixation, using -er, -est (morphological marking) or by periphrastic constructions involving more, most modifiers preceding the adjective (syntactic marking). The three inflectional forms are known as
* absolute (or positive)
*
comparative *
superlativeLower degree comparisons only use periphrastic constructions involving less and least adjectival modifiers.
Examples:/Inflectional / Periphrastic Same degree (Absolute) / tall / beautiful
Higher degree Comparative / taller / more beautiful
Superlative / tallest / most beautiful
Lower degree / – / less tall, less beautiful
/ – / least tall, least beautiful
