Comparative Adjectives

A comparative adjective measures a difference between two people, things, or groups. The standard pattern is: Noun 1 + linking verb + comparative adjective + than + Noun 2. Everest is taller than Fuji, This book is more interesting than that one. Unlike the base Positive degree, which simply describes (the mountain is tall), the comparative always implies a relationship—without the second term, the comparison is incomplete.

Formation follows the rules laid out in Degrees of Comparison: one-syllable adjectives take -er (smaller, faster), three-syllable adjectives take more (more beautiful, more intelligent), and two-syllable adjectives vary, with many accepting either form (cleverer or more clever). Crucially, only gradable adjectives—those describing qualities that can exist on a scale—can form comparatives. Absolute or non-gradable adjectives like perfect, dead, unique, or pregnant resist comparison: more perfect is logically suspect, though it appears in rhetorical and informal speech.

English offers a rich set of intensifiers and downtoners to adjust the strength of a comparison. Much taller, far more expensive, a lot heavier, a bit warmer, and a little easier all colour the degree of difference. These small words add precision and nuance that make speech sound natural rather than mechanical.

Comparisons of equality use the construction as + adjective + as: She is as tall as her brother. To express inequality, use not as + adjective + as or less + adjective + than: This route is not as fast as the highway or This route is less direct than the highway. The not as...as pattern is more common in everyday speech; the less...than pattern tends to appear in more formal registers. For comparisons involving three or more items, see Superlative Adjectives.
