Most bad dialogue fails in the same way: it sounds written. Characters explain things they already know, speak in complete paragraphs, and use words no one uses out loud. Real conversation is messier — people interrupt each other, trail off, answer a different question than the one they were asked, and say the opposite of what they mean. Learning to capture that mess, without making it unreadable, is the core skill of writing dialogue.

The fastest way to improve dialogue is to listen deliberately. Sit in a café, ride a bus, or listen to a podcast interview, and notice the patterns: fragments, false starts, filler words used sparingly, and sentences that change direction halfway through. Notice how rarely people say each other's names in conversation, and how often they communicate through implication — a short answer, a pause, a change of subject — rather than stating feelings directly.

Every character should be identifiable by their dialogue alone, without a name tag. That does not mean giving everyone a heavy accent or a catchphrase. It means giving each character a distinct rhythm, vocabulary, and set of concerns: one person speaks in short, blunt sentences; another hedges everything; another talks around the point. Read your dialogue aloud with the names covered — if you cannot tell who is speaking, the voices need more work.

Subtext is what a character means but does not say, and it is what makes dialogue feel alive. When a character says “I'm fine” while packing a bag, the reader understands more than the words alone. Avoid having characters announce their emotions or explain the plot to each other — “As you know, we have been married for ten years and your brother stole the company” is exposition wearing a dialogue costume. Trust the reader to infer from context, action, and what is left unsaid.

Real conversations are not polite turn-taking exercises. People talk over each other, finish each other's sentences, and respond to what they expected to hear rather than what was actually said. Using interruptions, trailing sentences, and brief overlaps — sparingly, so the scene stays readable — adds energy and realism. A character who never lets anyone finish a sentence tells the reader a great deal about that character without a single line of description.

Dialogue should be more interesting than real conversation, not a transcript of it. Cut greetings, small talk, and repetitions unless they reveal character or tension. Enter a scene late and leave early: start after the pleasantries and end before the conversation winds down naturally. If a line of dialogue does not reveal character, advance the story, or create tension, it probably does not need to be there.

The final test is simple: read the dialogue aloud. If you stumble, if a sentence feels like something no one would ever say, or if you run out of breath, rewrite it. Actors and editors both use this test because the ear catches what the eye misses. Dialogue that survives being spoken aloud is usually dialogue that will feel natural on the page.

Dialogue tags deserve restraint. The word said is nearly invisible to readers, which is a strength — it identifies the speaker without drawing attention to itself. Replacing every said with a colourful alternative like exclaimed, interjected, or opined quickly becomes distracting. Instead, use action beats to show how a line is delivered: she set the glass down, he looked away. A beat does double duty, revealing emotion and grounding the scene in physical action, while keeping the dialogue itself clean. Save unusual tags for moments where they genuinely add meaning, and let the words and the context carry the rest.
