Collaborate or Corroborate?

Collaborate means to work with someone else.

Corroborate means to find additional evidence for something.

I got these confused this week. Not exactly. What I did was use the wrong one.

I have been trying to corroborate the information I found on the benefits of hypnosis therapy for dementia. But I was saying I needed to collaborate this information.

Collaborate -- to work jointly with others, especially in an intellectual endeavor; to cooperate. From Latin.

Corroborate -- to support with evidence or authority, to confirm. From Latin.
