Hedge words are terms or phrases that create ambiguity or uncertainty in communication. They allow speakers or writers to soften their statements, making them less definitive. Common examples include words like "might," "could," "possibly," and "usually." By using hedge words, individuals can express opinions or predictions without committing to a specific outcome. In academic writing and research, hedge words are often employed to indicate that findings are not absolute. This cautious language helps to acknowledge limitations and variability in data. For instance, a study on climate change might state that temperatures "could rise" rather than asserting they "will rise," reflecting the inherent uncertainties in scientific predictions.
