Explain the concept of complementary gradable antonyms.

Complementary gradable antonyms are pairs of words that represent opposite ends of a spectrum or scale. These antonyms are used to describe qualities or characteristics that can vary in degree.

For example, the words "hot" and "cold" are complementary gradable antonyms because they represent opposite ends of the temperature spectrum. Similarly, "big" and "small" are complementary gradable antonyms as they describe the opposite ends of the size scale.

What sets complementary gradable antonyms apart from other types of antonyms is that they allow for degrees of comparison or measurement. In other words, there can be varying degrees of hotness, coldness, bigness, or smallness.

These antonyms are often used in comparative and superlative forms to express different levels of intensity or magnitude. For instance, we can say "It's hotter today than yesterday" or "This is the smallest car in the lot."

In summary, complementary gradable antonyms are pairs of words that represent opposite ends of a spectrum and allow for degrees of comparison or measurement. They are used to describe qualities or characteristics that can vary in intensity or magnitude.
