adverbialcomparative

An adverbial comparative is a construction in which an adverb is in the comparative degree and functions as an adverbial modifier to express a relative degree of an action or state. It compares how something is done, rather than describing a property of a noun.

Formation and patterns: adverbial comparatives are formed in two main ways. Many one-syllable adverbs and some that behave like adverbs take the -er form for the comparative (for example, faster, harder). More commonly, adverbs ending in -ly use more or less to form the comparative (more carefully, more quickly, more slowly). Some adverbs have irregular comparisons (well → better, badly → worse) and may appear in both adjective-like and adverbial senses. In addition to explicit than-clauses, equality of degree can be expressed with the correlative structure as ... as (as quickly as possible, as often as needed).

Usage and examples: adverbial comparatives modify the action or event rather than a noun. Examples include: She spoke more quietly than before. He ran faster than his rival. They completed the task more efficiently than expected. We can also compare frequency or degree with more; for instance, They work more diligently than their colleagues. Equality of degree is shown with as... as, as quickly as possible, or as often as needed.

Syntactic scope: the adverbial comparative primarily modifies a verb or verb phrase, and the comparison is typically introduced by than or framed by as... as. It can appear in main clauses or in comparative clauses, and it interacts with other degree words such as very or too.

Notes: not all adverbs admit a simple -er form, and some constructions are preferred for clarity. Avoid the erroneous combination more faster in most cases. The concept focuses on how the manner, frequency, or degree of an action is compared rather than the properties of nouns.
