Collaborate vs. Corroborate – What’s the Difference?

When you work together with people toward a shared goal, are you corroborating with them, or collaborating with them?

Likewise, what are you doing when you confirm someone else’s telling of events with your own account of what happened?

If you cannot decide which word refers to which scenario, you are not alone. All writers misuse words, and collaborate and corroborate are easy words to confuse. They sound very similar, and they are not commonly used verbs.
