Here's a breakdown of the meaning:
* Ill-chosen word: A word that is inappropriate, offensive, or simply doesn't make sense in the context of the conversation.
* Fool: Someone who lacks common sense or intelligence.
* Messenger: Someone who carries a message.
The proverb suggests that a foolish person's words are like a messenger carrying a message that reveals their lack of wit, wisdom, or tact.
In other words, if someone says something stupid or offensive, it's likely a sign that they are not very smart or thoughtful.
Here are some examples of how this proverb might apply:
* A child might blurt out an embarrassing truth about a family member, revealing their lack of social awareness.
* An angry person might use insults or swear words, revealing their lack of self-control.
* A politician might make a careless statement that reveals their lack of understanding of an issue.
The proverb reminds us to be careful with our words and to consider the impact they might have on others.
