Main Meaning
Definition
Dialogue (or dialog) is a noun with several related meanings. It refers to a conversation between two or more people, the spoken lines in a literary or dramatic work, or an exchange of ideas aimed at resolving a disagreement . As a verb, it means to take part in a conversation or discussion. In computing, “dialog” specifically refers to a window that prompts the user for input or displays information .
Origin
The word traces to the Greek dialogos, formed from dia- (“through”) and legein (“to speak”). It entered English through Old French and Latin in the 13th century . The spelling with “-ogue” reflects the French influence, while “-og” reflects a simplified American adaptation. The same pattern appears in other words: catalog/catalogue, analog/analogue, and monolog/monologue.
Context
The spelling choice depends on several factors:
- British, Canadian, and Australian English: Always use “dialogue”
- American English, general writing: “Dialogue” is preferred by most style guides, including AP Style

- American English, technical writing: Some guides distinguish “dialogue” for conversation and “dialog” for computers
Modern Usage
