1. To recite something that is written down. A noun or pronoun can be used between "read" and "out." The teacher read out the names of those who were selected to participate in the event. Read the letter out so I can hear what they wrote about your application.

2. To scold, upbraid, or chastise someone. Usually followed by "for (doing something)." A noun or pronoun is used between "read" and "out." Students either complain that I don't go into enough detail or else read me out for being too technical for them to follow along! The boss started reading me out for mixing up the information during the presentation.

3. To read the entirety of what one has to say. A play on the more common term "hear (one) out." A noun or pronoun is used between "read" and "out." I know that was a lengthy tangent, but thanks for reading me out. I know you don't agree with that user most of the time, but I think you should read her out. She actually makes some really informative posts on this forum.
