95 Synonyms for Difficult: List of Difficult Synonyms and Definitions

As writers, it is incredibly important to be able to communicate the same thought or emotion in several different ways—and to do so in a meaningful way.

When an author uses a vague word or is too repetitive in language, it doesn’t help to engage the reader. More often than not, it causes a thin layer of glaze to form around the eyes, as the reader loses focus and becomes increasingly unable to power through the written work.

Unfortunately, we all, at times, fall victim to this while writing, as it’s easy to rely on those words and phrases with which we’re familiar. But, today, I want to provide you with some relief in your search for a more meaningful, powerful way forward.
