を最後に

を最後に is used to indicate that something ends after a particular event or time, and does not continue afterward.

It emphasizes that the specified noun is the final occurrence, and that no similar action or event happens after it. Compared to similar expressions, を最後に is slightly less formal than を限りに, but still mainly used in written or serious contexts.

This grammar is commonly used to describe:

• Final meetings or appearances

• Last events or actions

• The point after which something completely stops
