What should I say for' this water is cold'? This is cold water =هذا ماء بارد This water is cold =هذا الماء بارد Correct?
In Arabic, we say "this the" to say "this." So "this the banana" just means "this banana." To say "This is the banana," this sentence could work depending on the context, but normally we'd say: هذه هي الموزة.
