We translate it as "is/was [done]" — e.g. "was created", "is known".

وَسَيُجَنَّبُهَا (But will be removed from it) uses form II (فَعَّلَ) — the middle letter is doubled, which makes the meaning stronger or causative.

The meaning is more intense than the basic form, or means "to make someone do [action]".

وَسَيُجَنَّبُهَا (But will be removed from it) starts with وَ, the most common Arabic word — it means "and".

We add "and" to connect this to what came before.
