When you are safely aboard a vessel, like a cruise ship, are you onboard or on board? What about when you agree with someone’s inspiring plan to save the world? Are you onboard or on board? Actually, the answer to both of those questions is the same. On board and onboard have distinct usage cases, and both of those examples just happened to be situations where on board is correct. Confused yet? Don’t worry—I’ll explain it all below.
In this post, I will compare on board vs. onboard. I will use each term in at least one example sentence, so you can see them in context. Plus, I will show you a helpful memory tool that will make choosing on board or onboard a little easier.
Onboard as adjective:
Onboard as verb:
Onboard is also used as a verb which means to go through procedures to effectively integrate (a new employee) into an organization or familiarize (a new customer or client) with one's products or services.
Onboard or on board:
These usages contain all the same letters, but they should be kept separate. Onboard is an adjective that means attached, and a verb that means to acclimate new hires to a new company. On board is an adverb or prepositional phrase that means safely aboard a vessel or in agreement. Now, let’s go over a trick to remember onboard vs. on board. Use onboard as an adjective before the noun it modifies. The phrase on board is an adverb or a prepositional phrase, and it usually goes after a verb. Since onboard is a single two-syllable word, like before, I predict you will experience only minimal difficulty remembering to use onboard before nouns.
