exemplar

Something fit to be imitated; an ideal, a worthy model or role model: a desirable example.

A ray of light amid all this nonsense was Gwyn Topham's piece in the Guardian, which was timely, measured, accurate and of appropriate tone. That this single report stood out so clearly as an exemplar is a scathing comment in itself on the volumes of drivel surrounding it.

Something typical or representative; an example that typifies its class.

A pattern after which others should be made; an archetype.

A well-known use of a scientific theory.

A manuscript used by a scribe to make a handwritten copy; the original document to be reproduced in a copy machine.

Exemplary.

In our age we have no patterne of motherly affection more exemplare, than yours.
