The document compares the three degrees of comparison in English: positive, comparative, and superlative. The positive degree uses words like "as" and "same as" to compare two things as equals or differences. The comparative degree uses suffixes like "-er" or "more" to compare two things. The superlative degree uses "the" plus "-est" or "most" to compare things among three or more items and indicate the one that is most or least. Examples are provided for each degree.
