What is the difference in antonym context clue and synonym context clue?

Antonym context clues provide hints about a Word's meaning by presenting its opposite, helping readers infer its meaning through contrast. For example, "She was elated, unlike her friend who was despondent." In contrast, synonym context clues offer similar Words or phrases that clarify meaning. An example would be, "The weather was torrid, or extremely hot, during our vacation."
