You don't need any particular language skill. That's up to you. What you need is spiritual advancement. The more you advance spiritually, the more understanding you'll gather of the universe and life in general, not just the enemy. Like someone already said, the enemy is not worth of your attention to that degree.
The only attention they're worth of is the mind we pay to them once we do spiritual warfare. After the ritual has ended, you just remove them from your mind until the next ritual. Any uplifting we do toward the human species at large is because that's human nature when we focus on the divine, Father Satan-given elements within us. It's not because the enemy is here. If the enemy wasn't here, we would still be working to massively benefit humankind, onward and upward.
