Use of the preposition off
1. Off as an Indicator of Physical Separation or Removal:
This is arguably the most fundamental use of “off.” It signifies a detachment or distance from a surface, object, or place.

- Example: “He took the book off the shelf.” (The book was previously on the shelf, but is now removed.)

2. Off Indicating Direction or Departure:
In this context, “off” signals movement away from a specific point or towards a different location. It implies a separation and a subsequent trajectory.

In this case, “off” indicates the end of an activity, a state, or a period of time. It signifies a stopping or discontinuing of something.

- Example: “The project was called off due to lack of funding.” (The project was discontinued because of insufficient funding.)
5. Off Indicating Dependence or Reliance:
This usage can be a bit trickier, as it often appears in phrases and idioms. It suggests a reliance on something for support or success.
