A: The new manager has been talking about his new plans all day, but we know he is doing nothing more than paying lip service.

B: It’s true. I agree with you.

Note: This idiom refers to supporting an idea or a plan verbally, but doing nothing in reality. This term first appeared around the 15th and 16th centuries. “Lip+ (noun.)” was a general pattern at that time. For example, “lip wisdom” refers to the wisdom of those who do not practice what they preach; “lip religion” or “lip devotion” refers to prayer without genuine faith or desire.
