“Dialog” vs. “Dialogue”

In American English, dialog and dialogue can be different spelling variations of the same word. Or, they can have slightly different meanings altogether. It often depends on which style guide you’re following.

Dialogue is often used to refer to the conversation between two or more people that was written for and featured in a book, film, or play. It can also simply be a conversation between people (in real life, not in a book, film, or play).

The dialogue between the protagonist and antagonist was anticlimactic.
I can’t go out today; I have to rehearse the opening dialogue with Joseph.
We engaged in healthy dialogue and thought of ways to reduce littering.
“Dialogue” can be the conversation people have in real life or one that was written for a book or movie.

Dialog, on the other hand, is regularly used in a computing sense—dialog box.

A dialog box is a small window that appears on a screen where you can input text or select a command.

When the dialog box appears, click “Install LanguageTool.”

Some style guides suggest using the different spellings of “dialog” and “dialogue,” depending on what is being referred to.

Keep in mind that in American English, dialogue is the preferred spelling when referring to a conversation. However, dialog is an acceptable spelling, regardless of the context. Using dialogue or dialog is often a stylistic choice that depends on the style guide you’re following. For example, AP Stylebook recommends “dialogue,” regardless of meaning. What’s important is that you don’t jump around from one variation to another within the same text. Choose one and stick with it.
