1. Use the word "gasp" itself as an interjection. For example:
> "What did you just say?" she gasped.
2. Use descriptive words to convey a sense of surprise or shock. For example:
> She gasped, her eyes widening in disbelief.
> He sucked in a sharp breath, his jawdropping.
3. Use punctuation marks such as exclamation marks or dashes to emphasize the gasp. For example:
> "I can't believe it!" she gasped.
> "No way!" he exclaimed, gasping.
4. Combine different techniques to create a more dramatic effect. For example:
> "You're kidding, right?!" she gasped, her eyes widening in shock.
5. Use dialogue tags to indicate that a character is gasping. For example:
> "Wait, what?" she gasped. "Are you sure?"
> He gasped in disbelief. "This can't be true!"
By using these techniques, you can effectively convey the emotion of surprise or shock through dialogue and create a sense of suspense or drama in your writing.
