A white lie的意思

"A white lie" is an English idiom that refers to a lie that is considered to be harmless or well-intentioned. It is usually told to avoid hurting someone's feelings or to maintain a positive social situation. Unlike a malicious or deceitful lie, a white lie is often seen as a minor transgression or a polite gesture. For example, saying that you like a friend's new haircut when you actually don't, to avoid upsetting them, could be considered a white lie.
