I attend a meeting where the phrase "during the duration of the meeting" is used and it sounds redundant. Seems like it should be " during the meeting" or "for the duration of the meeting.
Hello, Lance, and welcome to the Grammar Exchange!
Yes, "during the duration" is pretty silly. You are right that "for the duration of the meeting" would be a better choice. Another option is "throughout the meeting."
"During the meeting" can't be substituted for "for the duration of the meeting." Many things happen during a meeting that do not happen for its entire duration.
In the future, when you ask about particular phrases, please try to give an example sentence with the phrase. Thank you.
Understood and thanks
