Expert writing Tips
Best practice
Avoid using the phrase "thick to read". Opt for more grammatically correct and commonly understood alternatives such as "difficult to read" or "hard to read".
Common error
Do not use "thick" directly before "to read" to describe reading difficulty. "Thick" typically describes the physical dimensions of an object, not the cognitive challenge of reading. Instead, use adjectives that directly relate to difficulty, such as "challenging" or "complex".

Ludwig's WRAP-UP
In summary, while the phrase "thick to read" might seem like a straightforward way to describe something difficult to read, it is grammatically incorrect. Ludwig AI identifies it as such. It's best to use clearer and more common alternatives like "difficult to read" or "hard to read". Though sources like The New York Times and The Guardian appear in the search results, it is because the algorithm found the separate words "thick" and "to read" and not necessarily because they use the phrase "thick to read" as an established expression. Therefore, always opt for grammatically sound alternatives.
