Be right back!

I'll be back with your order.

vs.

I'll be right back with your order.

What's the difference between these two sentences? The first sentence is open-ended, meaning the person doesn't say WHEN they'll be back with your order. It could be 5 minutes later, it could be 5 hours later... you have no idea.

By using right you add EMPHASIS that the time will be short.

So you will often hear it when someone says they won't be long:

Be right with you in a sec!

meaning

I'll be with you in just a second.

She's coming over right now.

meaning

She is coming over at this moment.

So right now means without delay.

Do it right now.

meaning

Don't wait. Do it NOW.

One of the best uses of this is the expression.

Be Right Back

meaning

I'll be back very soon.

It is used so often that it became an acronym used in internet chat: BRB.

Have a nice weekend!
