good的最高級是best。形容詞的最高級前面要加定冠詞the，副詞最高級前面的the可以省略。 在含有最高級的句子中，常有一個in/of短語來表示比較范圍。屈折語一般用一定的屈折變化表示形容詞的比較。普通比較稱為比較級，最高比較稱為最高級。

The highest level of goodness is represented by the word “best.” The definite article “the” is used before the superlative form of an adjective, while the definite article can be omitted before the superlative form of an adverb. In sentences featuring the superlative degree, it is common to include a prepositional phrase like “in/of” to indicate the scope of comparison. Inflectional changes are typically used in inflected languages to express the comparative degree of adjectives. The comparative degree is used for normal comparisons, while the superlative degree is used for the highest level of comparison.
