Expert writing Tips
✓ Best practice
Always use the correct past participle form of the verb "confirm" – "confirmed" – when using the infinitive "to be" to ensure grammatical accuracy. For example, use "The date is to be confirmed" instead of "The date is to be confirm".
⚠ Common error
Avoid using the base form of the verb after "to be". The correct form is typically the past participle (for passive voice) or the present participle (for continuous tenses). For example, it's correct to say "The data needs to be analyzed" and incorrect to say "The data needs to be analyze".
Linguistic Context
The phrase "to be confirm" functions as an incorrect infinitive phrase. It attempts to express a future action that requires validation. However, the grammatical error undermines its intended function. As Ludwig AI explains, the correct form is to use the past participle.
