وَمَآءٍۢ (And water) has no ال and takes tanwīn (the "n" sound at the end), so it means "a" or "some" — not a specific one.

We translate it as "a/an" or leave it general.

وَمَآءٍۢ (And water) starts with وَ, the most common Arabic word — it means "and".

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