Different Meanings

The word "allograph" has two distinct, specialized meanings: 1. Legal/Administrative: A delegated signature. 2. Linguistic/Typographic: A visual form of a written unit.

Notes

• The two meanings originate from different roots: the signature meaning comes from "allo-" (other) + "-graph" (writing), while the linguistic meaning comes from the morphological concept of an "allomorph," applied to writing systems.
• It is a technical term primarily used in specialized fields like law, linguistics, and graphic design.
