Here's a breakdown:
* "Still tongue" refers to someone who doesn't talk much or doesn't gossip or speak carelessly.
* "Wise head" implies someone who is thoughtful, insightful, and makes good decisions.
The proverb suggests that:
* Thinking before speaking is important: By being silent, you have more time to consider your words and avoid saying things you might regret.
* Listening is essential for learning: Quietly observing and listening to others can make you more knowledgeable and understanding.
* Silence can be a sign of strength: Not feeling the need to constantly talk can be a sign of confidence and self-control.
However, it's important to note that the proverb can be misinterpreted as advocating for complete silence. Wise heads don't necessarily remain silent all the time. They speak when necessary, with clarity and purpose.
In essence, the proverb reminds us to be mindful of our words and to use our voices wisely, rather than just speaking for the sake of speaking.
