The transposition of a narrative or textual work into another medium or form that requires systematic transformation of content, structure, and expressive means so that the work functions according to the affordances, constraints, and conventions of the target medium.

Principle

Adaptation entails mapping narrative functions (plot points, characterization, perspective, thematic emphasis) onto the communicative affordances of the target medium; this mapping necessarily involves selective preservation, omission, reconfiguration, or invention because some narrative devices do not transfer directly across media.

Demonstration

Illustrative scenario → A prose narrative with extensive internal monologue is adapted for a visual medium: adapters represent inner thought through visual motifs, voiceover, or enacted dialogue, choose which episodes to dramatize, and restructure pacing for screen time → The adapted work communicates related themes and characters but alters sequence, emphasis, and some meanings to suit visual and temporal constraints.

Misapplication

Equating fidelity with success. The error is to assume that an adaptation must reproduce source details verbatim to be valid; this ignores medium‑specific affordances and the adapter’s interpretive role, and conflates literal sameness with effective transposition.

Consequence

Adaptation produces a distinct cultural artifact with its own interpretive frame: it can broaden audience reach, generate new meanings, and trigger different practical outcomes (legal rights, reception histories). It also requires evaluative criteria that account for medium‑specific effectiveness rather than strict textual fidelity.

Reversal

When the target and source media share near‑isomorphic affordances (e.g., between similar textual forms), transformation may be minimal and labeled translation or transcription rather than adaptation; conversely, transmedial projects designed as reinterpretations may intentionally diverge from source themes as a creative strategy.

Boundary

Clearly within: deliberate reworking of a novel into a film or a stage play that alters narrative structure to match medium constraints. Boundary case: a literal abridgement or editorial compression within the same medium—an editorial adaptation may not involve cross‑medium transformation. Clearly outside: simple reproduction without medium change (reprinting) or unauthorized copying presented as original.

Semantic Tension

Tension between fidelity to source material (authenticity, fan expectations) and creative reinterpretation or medium‑specific optimization (innovation, communicative adequacy).

Synthesis

Adaptation is an interpretive act that both translates and transforms: it demonstrates that narrative identity is not fixed to form but constituted through medium‑sensitive choices that create a new, autonomous work shaped by different constraints and possibilities.
