Questions & Answers about Αν ισχύει ο νέος κανόνας, θα χρειαστεί και υπογραφή στο τέλος.
Why does the sentence start with Αν and what exactly does Αν ισχύει... mean grammatically?
Αν introduces a conditional clause (if...).
In Αν ισχύει ο νέος κανόνας, the verb ισχύει is in the present tense, so the condition is phrased as “if the new rule is valid / is in force (at the relevant time).”
This is a very common pattern: Αν + present (condition) → θα + verb (result).
Could it be εάν instead of αν?
Yes. εάν is a slightly more formal/explicit variant of αν. In everyday writing and speech, αν is extremely common. The meaning is the same in this sentence.
Why is there a comma after κανόνας?
Greek typically uses a comma to separate an introductory conditional clause from the main clause, especially when the Αν... clause comes first:
- Αν ισχύει ο νέος κανόνας, (condition)
- θα χρειαστεί... (result)
The comma is standard and helps readability.
