Expert writing Tips

Best practice

When using "hard constraint", ensure it's genuinely inflexible. If there's any flexibility, consider using terms like "soft constraint" or "guideline".

Common error

Avoid using "hard constraint" when a "soft constraint" is more appropriate. A "soft constraint" is a guideline that can be bent or broken under certain circumstances, while a "hard constraint" is an absolute requirement.

Linguistic Context

The phrase "hard constraint" functions as a noun phrase, typically serving as the subject or object of a sentence. It identifies a specific type of limitation or requirement, as demonstrated in Ludwig's examples.
