For example, there are two cakes in front of you, one is baked, another unbaked, steamed, or made in some other particular ways. But you would like to try the baked one, but not the others.The phrase 'a baked cake' would be understood, but I can't imagine a context in which you would use it because cakes are always baked – that's what a cake is: a baked product.
Yes, because tautology is considered a linguistic fault. If your assumption is that all cakes are baked, you should not say "a baked cake".Thanks, Chez. It seems that there must be something that has a feature to be compared to that of the entity denoted by such a phrase, say, 'a baked cake'. Am I right?
Thanks. This reminds me of the fact that adjectives or any other modifiers are used to distinguish one thing from another. If all the things are the same, there is no need to use an adjective to 'differentiate' them.... If your assumption is that all cakes are baked, you should not say "a baked cake".
