Choosing between decide · choose

Decide is about reaching a conclusion, often about what to do: We decided to leave early. Choose is about picking one thing from a set: She chose the blue dress. With a to-infinitive, decide is much more usual: He decided to study law.

Common mistakes

I decided going home. I decided to go home.
Decide is followed by a to-infinitive, not an -ing form.
We decided about the date of the party. We decided on the date of the party.
Use decide on when you choose one thing from several possibilities.

For translators

Grammar trap Decide takes a to-infinitive (decide to go) and on before a noun that is chosen (decide on a name); many languages use a different preposition or none.
