When writing, it's important to keep your language varied and interesting. One way to do this is by using synonyms for common phrases like "one says". Some alternatives to consider include "according to", "as stated by", "reportedly", "allegedly", "as claimed by", and "purportedly". Using these synonyms can add depth and nuance to your writing, while also keeping your readers engaged. Additionally, avoiding repetitive language can help to avoid reader fatigue, making your writing more enjoyable and accessible. Don't be afraid to branch out and experiment with different phrasing to keep your writing fresh and engaging.
