Expert writing Tips

Best practice

Use "thought for sure" to convey a sense of strong belief or expectation, but be mindful of the context. It's suitable for informal communication and narratives where a character expresses their assumptions. In formal writing, consider more precise alternatives like "was certain" or "fully expected".

Common error

While "thought for sure" is acceptable, avoid overusing it in formal writing. Over-reliance can make your writing sound less professional. Mix it up with alternatives like "was convinced" or "believed strongly" to maintain a sophisticated tone.
