I would like to express the following idea in a more fashionable and eloquent manner:

> 
> leave on a break of unknown duration / take a break... / leave on
>  hiatus...
> 
> 
> 

Use of the highest linguistic register, highest level of formality and even archaic style are blissfully accepted.

Please be at liberty to change any part of this sentence and note as well that the duration is unknown and may span great lengths.

This is not a break from school, but a discontinuation of a certain activity for some time, a sign or a message, for example, to note one's leave.
