Ngôn ngữ dè dặt (hedging): tentative claims, epistemic modality

# Hedging Language (tentative claims, epistemic modality, stance)

Hedging, also known as epistemic modality or stance, is a linguistic strategy used to express uncertainty, caution, or politeness in academic writing. It allows writers to make claims that are not absolute, thereby protecting them from potential criticism and demonstrating a nuanced understanding of the topic. Hedging is a hallmark of C1-level academic English and is essential for achieving a high IELTS score (Band 7.0+).

Why Use Hedging?

• Avoid overgeneralization: Acknowledge that exceptions may exist.
• Show respect for alternative views: Indicate that your claim is one of several possibilities.
• Increase credibility: Tentative language signals careful, evidence-based reasoning.
• Meet academic conventions: Most scholarly writing requires a cautious tone.
