Expert writing Tips
Best practice
When using "core reason for the", ensure that it truly represents the most fundamental or primary reason, not just a contributing factor. If other conditions are needed to support that reason, it may be better to say primary or underlying reason.
Common error
Avoid using "core reason for the" when there are multiple significant factors involved. If the reason is one of many contributing elements, use a phrase like "a key factor in" instead to avoid implying it is the sole or most important reason.
