The referential theory of meaning states that the meaning of a word is the object or concept to which it refers. The descriptive theory of meaning states that the meaning of a word is the set of properties that it describes. The verificationist theory of meaning states that the meaning of a word is the method by which its truth or falsity can be determined.

In order for a statement to be true, it must have a meaning. However, a statement can have a meaning without being true. For example, the statement "The sky is green" has a meaning, but it is not true.

The statement "The Earth is flat" has a meaning, but it is not true. The Earth is actually a sphere.

All of the statements listed have a meaning. Therefore, there is no example of a statement that is true but does not have a meaning.

A semantic truth is a statement that is true in all possible worlds, regardless of the circumstances. A pragmatic truth is a statement that is true in some possible worlds but not in others, depending on the circumstances.

None of the statements listed are semantic truths. The sky is not always blue, the sun is not always a star, and the Earth is not flat.

The statement "The sky is blue" is a pragmatic truth. It is true in most cases, but it is not true in all cases. For example, the sky can be gray or black on a cloudy day.

The meaning of a word determines its reference. For example, the word "dog" refers to all and only dogs. This is because the meaning of the word "dog" includes the properties of being a canine, having four legs, and barking.

The meaning of the words "dog", "cat", and "tree" all determine their reference. The word "dog" refers to all and only dogs, the word "cat" refers to all and only cats, and the word "tree" refers to all and only trees.

There are no words whose reference determines their meaning. The meaning of a word is always determined by its reference.
