Questions & Answers about Sie werden es gefälligst unterlassen, ohne sich zu beschweren!
What exactly does gefälligst do in this sentence?
The particle gefälligst turns a regular command into a highly annoyed, aggressive demand. It roughly translates to "damn well" or "kindly" (in a strictly sarcastic way). It comes from the adjective gefällig (pleasing or obliging), but in modern German it is used to express severe irritation when ordering someone around.
Why use the future tense (Sie werden ... unterlassen) for an immediate command?
In German, using the future tense (werden + infinitive) is a way to give a strict, undeniable order. It implies that the action is inevitable because the speaker leaves absolutely no room for refusal. Combined with gefälligst, it sounds much more authoritative and severe than a standard imperative like Unterlassen Sie es!
Is unterlassen a separable or inseparable verb?
It is inseparable. Even though unter can sometimes be a separable prefix, in unterlassen (to refrain from / to cease) it is permanently attached. Because it is inseparable, the spoken stress falls on the second part of the word, and it does not use a -ge- in its past participle.
Why is sich included in the ohne ... zu (without doing X) clause?
