Expert writing Tips

Best practice

Use "could exist" to express a possibility or hypothetical situation. It's appropriate when discussing theories, potential scenarios, or unproven concepts. For example, "Life "could exist" on other planets" suggests it's a possibility, not a certainty.

Common error

Avoid using "could exist" when you want to express a definite fact or highly probable event. "The evidence shows that a problem "could exist"" implies more doubt than may be warranted if strong evidence is present. Instead, use "does exist" or "likely exists" to reflect a higher degree of certainty.

Linguistic Context

The phrase "could exist" functions as a modal verb phrase, expressing possibility or potential. It combines the modal verb "could" with the infinitive verb "exist" to indicate that something may be present or occur, but is not certain. Ludwig provides numerous examples illustrating this usage.
