Comparison

Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to some other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to all other comparators.

Morphological Comparison
Comparatives and superlatives may be formed in morphology by inflection, as with the English and German -er and -(e)st forms and Latin's -ior (superior, excelsior).

The usage of morphological comparison are used on "basic" adjectives. Some examples include:

Syntactical Comparison
In syntactic construction, inserting the words "more" or "most" before an adjective or adverb modifies the resulting phrase to express a relative (specifically, greater) degree of that property. Similarly, inserting the diminutives "less" or "least" before an adjective or adverb expresses a lesser degree.

Syntactical Comparison is usually used on "less basic" adjectives or adverbs.
