What does "to wander off" mean in English?

The phrase "to wander off" typically means to leave a place in a casual or aimless manner, often without permission or without a specific destination in mind. This aligns with the idea of leaving unauthorized, indicating that the person is moving away from where they are supposed to be, sometimes without the intent to return immediately or at all.

The other options do not capture the essence of this phrase. The notions of coming back quickly, remaining in one place, or standing still all imply a sense of stability and intentionality that contradicts the meaning of wandering off, which focuses on movement away from a designated area rather than remaining or quickly returning.
