Best practice

When using "primary reason", ensure that it truly represents the most significant cause or justification, and not just one of several contributing factors. Be prepared to support this claim with evidence.

Common error

Avoid using "primary reason" when there are multiple significant factors at play. If the reason you're citing is only marginally more important than others, it's more accurate to describe it as 'a major reason' or 'one of the primary reasons'.

As Ludwig AI confirms, it is a common and grammatically correct expression. For example, 'The primary reason for the delay was...' shows it acting as the subject complement.
