Common Mistakes to Avoid

Assuming all synonyms are interchangeable

While synonyms have similar meanings, they often have different connotations or usage contexts. “Childish” and “youthful” both relate to being young, but have very different implications.

Overusing complex synonyms

Don’t use a complicated synonym when a simple word works better. “Use” is often clearer than “utilize” in most contexts.

Ignoring context with antonyms

The antonym of “light” could be “dark” (brightness) or “heavy” (weight). Context determines the correct opposite.
