Fin vs. bout
The French words fin and bout can both be translated as end in English, but they are not interchangeable. The key difference lies in whether the end is abstract and temporal or physical and concrete.
Fin
A2The word fin refers to the end of a period of time, an action, a process, or a concept. It marks the point of completion or cessation and is generally abstract or temporal. It can also refer to a goal or purpose, as in the expression the end justifies the means.

Bout
A2The word bout refers to the physical end, tip, or extremity of a concrete object. It is something you can often touch. It can also be used to mean a piece or a bit of something. In the special expression au bout de, it can refer to the end of a duration of time.

Summary
In summary, use fin for abstract or temporal endings, such as the end of a day, a film, or an era. It signifies conclusion or cessation. Use bout for the physical extremity of a concrete object, like the end of a street or a pencil. Remember that bout can also mean a piece, and the expression au bout de is a common way to talk about the passing of a specific duration of time.
