 Frege (1918a [TFR: 329]) held that an assertion is an outward sign of a judgment (Urteil). A judgment in turn, in Frege’s view, is a step from entertaining a Thought to acknowledging its truth (Frege 1892 [TPW:  64]).[11]  The subject first merely thinks the Thought that p, and then, at the judgment stage, moves on to acknowledge it as true. Since for Frege, the truth value is the reference (Bedeutung) of a sentence, a judgment is an advance from the sense of a sentence to its reference. In case the subject makes a mistake, it is not the actual reference, but the reference the subject takes it to have.
