Welcome to English in a Minute. When we get on board a plane, train, or boat, we physically get on the vehicle.
But to get on board has another meaning too.
Hey Anna, I thought of a great new idea for work.
Dan, please. Work is busy enough. No more ideas.
Oh, you'll get on board with this idea.
What we need is more free time, not more ideas.
Well, my idea is free time Fridays.
Oh, yeah. Oh, I can totally get on board with that idea.
If you get on board with an idea, you like it. You agree with it.
You can also get on board with a process or activity that you want to take part in.
And that's English in a Minute.
