Signersigned

Signersigned is a coined term used to describe something that has been endorsed or authenticated by a particular signer. In practice, it can function as an adjective (a signersigned manuscript) or as a noun phrase (a signersigned edition). The form emphasizes the identity of the signer and the act of signature as the source of legitimacy.

Usage varies by field. In legal and administrative contexts, the document is described as signed by a named party; the phrase signersigned is less common and often replaced by “signed by [name].” In scholarly or cataloging work, signersigned may appear to note authorship, endorsement, or provenance, for example in manuscripts, certificates, or art, where a specific individual's signature is a critical attribute for authenticity.

In the digital arena, the idea maps to digitally signed data. A signersigned digital artifact carries a cryptographic signature generated with the signer's private key and verifiable with the corresponding public key, providing integrity and non-repudiation. Some projects use the term informally to distinguish items bearing the official signature of a person of record from unsigned copies.

Etymology: signersigned is a portmanteau or compound formation blending signer and signed; it lacks a long-established place in standard English technical vocabulary, and its acceptance depends on discipline and audience.
