An unintended alteration introduced into a text, record, or message during copying, printing, encoding, oral relay, or other relaying processes, typically localized to specific witnesses or transfers and not the result of deliberate revision.

Principle

Transmission errors are stochastic and context-specific: they tend to appear irregularly across witnesses and can be identified by patterns of inconsistency that do not align with systematic linguistic or editorial change.

Demonstration

Illustrative scenario: Two manuscript witnesses agree on a reading; a third omits a short clause. Collation shows the omission occurs only in that witness’s line of descent, indicating a localized copying error rather than an authorial variant.

Misapplication

Interpreting a transmission error as an authorial variant, editorial choice, or evidence of dialectal change; the semantic error is treating an accidental, localized difference as representative of the original composition.

Consequence

Requires textual-critical methods (collation, stemmatic analysis, conjectural emendation) for restoration or annotation; if unrecognized, such errors can change meaning, mislead interpretation, or corrupt datasets used for analysis.

Reversal

Some variations that appear accidental may instead be deliberate (author revision, editorial modernization) or the result of systematic orthographic conventions; such cases qualify the assumption that all nonconforming readings are errors.

Boundary

Clearly within: an isolated omission, transposition, or graphic error traceable to a single copying chain. Boundary case: a repeated misreading by multiple scribes due to an ambiguous exemplar. Clearly outside: deliberate redaction, authorized modernization, or variant composed by the author.

Semantic Tension

Fidelity to an ideal original ↔ Pragmatic need for comprehensibility (editors may emend to restore sense, trading fidelity for clarity).

Synthesis

Transmission error is a diagnostic category for accidental, localized corruptions; distinguishing it from systematic change or deliberate alteration depends on witness patterns and editorial evidence rather than on a single divergent reading.
