Example: "To clarify my argument, let me provide a definite example of how this theory applies in real life."
Alternatives: "a clear example" or "a specific instance".
Overall, we suspect that stop-loss mutations of uORFs are likely to represent an under-recognized class of hypomorphic mutations, although a search of the Human Gene Mutation Database (HGMD) (see Materials and Methods) did not yield any definite examples.

Kripke only considered names that were introduced using a definite description (for instance, Evans' [1979] example of the introduction of 'Julius' to refer to the inventor of the zip), and so had a determinate reference (and intension).
Most of these examples involve a definite description, which is used to "fix the reference" (Kripke 1980, pp. 54 6, 135), and not as a synonym: the term is to apply to the designatum even with respect worlds in which it does not satisfy the description.
