drift

To drift means to move slowly, usually without firm control or a clear direction, often because something else is carrying you along. It can describe physical movement, like a boat drifting on the water: "The small sailboat drifted with the tide." It can also describe movement in the air, as when smoke drifts toward a window or clouds drift across the sky.

The word is also common in less physical ways. Your mind can drift during a long meeting. You can drift off to sleep. A conversation can drift from one subject to another. In these cases, the idea is the same: there is slow movement away from the starting point, without anyone strongly guiding it.

Drift can also suggest a slow change in life or behavior. Someone might drift away from old friends, drift into a new job, or drift through their twenties without a clear plan. This gives the word a quiet, passive feeling. Things are changing, but not through a sharp decision.

As a noun, drift has a few related uses. It can mean a mass driven together by wind or water, as in a snowdrift. It can also mean the general direction or basic meaning of something. If you say, "I get the drift," you mean you understand the main point.

So whether you are talking about boats, smoke, sleep, thoughts, conversations, or life itself, drift is a word for slow movement and gentle change, often without a fixed course.
