Prepositions after verbs

Embark on, upon, at, for or in?

Embark is usually followed by on or the more formal upon when talking about a project, journey, or activity. Other prepositions may appear in the sentence for time or place, not as part of the verb pattern.

Quick answer

Which preposition follows embark?

Use embark on for most modern English contexts: embark on a journey, embark on a career, embark on negotiations. Embark upon is more formal. Prepositions such as at, for, and in usually add separate information about place, purpose, or situation rather than forming a fixed combination with embark.

They embarked on a new marketing campaign.
She embarked upon a detailed investigation.
We embarked at the south terminal before dawn.
