Degrees of Comparison
There are three degrees of comparison in Russian: positive, comparative and superlative.
The posititive degree simply describes a quality. Adjectives are given in dictionaries in positive degree.
The comparative degree: the adjective compares the qualities of two nouns.
The superlative degree is the form of an adjective which denotes that something has a quality to a greater degree than anything.
Comparative and superlative forms of adjectives are created by adding an ending to the stem (simple comparative and simple superlative) or with help of special adverbs, equivalent of English "more" and "most" (compound comparative and compound superlative)
