What does "benefit of something" mean? Is it general expression?
To "give someone the benefit of the doubt" is a common expression that means to trust or believe someone to be honest, until proven otherwise. In other words, it means trusting someone even if you are unsure if he/she is being honest. The speaker has used this expression in this video to accuse her sister of always being suspicious and doubtful of their mother, instead of trusting her. Ex: The employee said she was late because of a traffic jam, so her boss gave her the benefit of the doubt. Ex: Give me the benefit of the doubt. I have never lied to you.
