what do they mean. i come across several time on tv. what do they mean there we go and here we go.. i would be happy if you explain with example ..thanks
It may depend on the context.
"There we go!" can mean "Now we've got it."
"Here we go" can mean now we're going, or about to do something important or intimidating.
"Here we go again!" combined with a sigh or a roll of the eyes means that something is happening that has happened before and that we're not looking forward to. Maybe someone is repeating a complaint or argument that we have heard before.
