Comparison

Comparison is how English measures one thing against another — whether they're equal, whether one exceeds the other, or whether one falls short. It's a way of expressing relative quality, quantity, or manner, rather than stating a fact in isolation.

Grammatically, English organizes comparison around three degrees:

• Positive — the base form, no comparison involved: tall, expensive, quickly

• Comparative — comparing two things: taller, more expensive, more quickly

• Superlative — comparing one thing against a group of three or more: tallest, most expensive, most quickly

But comparison isn't limited to adjectives and adverbs — English also compares nouns and quantities (more books, less time), and offers several structures beyond the basic comparative/superlative system to express similarity, difference, or preference.

Before looking at each of these areas, we'll start with how comparative and superlative forms are actually built — the foundation everything else relies on.
