What is sight translation?

What is sight translation?
I received a lot of feedback from the language and interpreting community after I posted my first blog last month.

Here is a question I received regarding sight translation that I wanted to clarify:

Question: "So what is sight translation? In last month's blog, I thought you said translation was the written word and interpretation was the spoken word."

Answer: Yes....BUT sight translation is an oral interpretation of a document that an interpreter has reviewed, then verbally interprets the contents from one language to another to the client or before a judge or in other medical or social settings.
