The meaning beneath the surface of what characters say and do - the unspoken truth that the reader senses but nobody states directly.
Subtext is the implicit meaning that exists beneath the explicit content of dialogue, action, and description. It's everything your characters communicate without saying it outright. When a couple argues about whose turn it is to do the dishes, and the reader understands they're really arguing about whether their relationship is equal, that gap between surface and depth is subtext. The strongest writing operates on both levels simultaneously - what's said and what's meant.
Subtext is what separates writing that feels real from writing that feels on-the-nose. In real life, people rarely say exactly what they mean. They deflect, hint, avoid, perform, and talk around the thing they're actually feeling. Fiction that captures this behavior feels authentic, and it gives readers the pleasure of understanding more than the characters are willing to say. Subtext respects your reader's intelligence by letting them do some of the interpretive work.
The entire story is subtext. A couple discusses an 'operation' without ever naming what it is (an abortion). Everything important lives in what they don't say - their evasions, their non-answers, their small cruelties.
George and Martha weaponize social pleasantries, academic small talk, and party games. Every line of dialogue carries a second conversation about power, resentment, and the lies holding their marriage together.
Instead of 'I'm angry at you because you betrayed my trust,' try having the character do something that communicates the anger - a slammed door, an overly formal tone, a refusal to make eye contact. Let the reader figure out the rest.
Subtext that nobody catches isn't subtext - it's a secret. You need enough surface clues for an attentive reader to grasp what's really going on. The gap between surface and depth should be crossable.
If your dialogue beautifully avoids the real issue and then the narrator explains 'what she really meant was...,' you've undone all your work. Trust the dialogue. Trust the reader.
Write a dialogue scene between two people who are arguing about something trivial - what to eat for dinner, where to park the car, how to load the dishwasher. But beneath the surface, they're really arguing about something much bigger - a betrayal, a life decision, a fundamental incompatibility. Never mention the real issue directly. Read it back and ask: can a reader feel the real argument without anyone naming it?
Write between the lines.
