Pay lip service to的意思

"Pay lip service to" is an English idiom that means to give lip-only support or to express support for something without actually doing anything to back it up. It implies that the person is paying only superficial attention or is being insincere in their support. The phrase suggests that the person is not genuinely committed to the cause or idea, but is merely paying it lip service, which means they are saying the right things but not following through with actions.
