Ein gewaltsamer oder geplanter Angriff auf Menschen, Gebäude oder Einrichtungen, oft mit dem Ziel, Schaden zu verursachen oder Angst zu verbreiten.

Anschlag is a masculine German noun with several meanings, depending on context:

A planned violent attack or attempt, especially one directed at a person, group, or institution. It often appears in the phrase “to carry out an attack.”
A posted notice or announcement, such as a paper put up on a noticeboard. This meaning is less common.
A press or keystroke, especially the action or force of pressing a key on a keyboard.
A stop or limit in a mechanism: the point beyond which a moving part cannot go. In the expression “to the limit,” it can also mean “as much as possible.”

Article: der
Plural: die Anschläge
Word parts: an- + Schlag , from schlagen (“to strike” or “to hit”). The word’s different meanings are connected to the ideas of striking, pressing, or setting something against a limit.

There is no single synonym that fits every meaning.

For a violent attack: Angriff is a broader word for an attack; Attentat usually suggests a planned, politically motivated attack or assassination attempt.
For a posted notice: Aushang specifically means a notice displayed publicly; Bekanntmachung is a more formal announcement.
For a mechanical limit: Anschlag can sometimes be paraphrased as Begrenzung [?](vocabuo://word/Begrenzung], though this means a limit more generally.
