The comparative degree is a form of adjectives and adverbs used to compare two nouns. It typically adds the suffix “-er” to one-syllable words, such as “taller” or “faster.” For words with two or more syllables, the word “more” is used before the adjective, as in “more beautiful” or “more interesting.” In sentences, the comparative degree often follows the structure “A is [comparative adjective] than B.” For example, “Alice is taller than Bob.” This structure helps to highlight differences in qualities or characteristics between the two subjects being compared.
