Yes, and there we got the problem. Allah cannot be represented in other languages.
Friedrich Nietzsches point was that we often use the same term for different things. Yes, we need grammar, but still it's inaccurate and often misguiding, especially in issues of metaphysics. Platon said for example that we have endless ideas of different things, but we use the same term to describe it. We say "tree" to a show a specific tree, but we also describe all other trees as "trees", even they differ heavily. Still we use the same term. Human language, even it's a great instrument of communication, it's still superficial and trivial.
