Which word describes something that causes annoyance or anger deliberately?

The word that best describes something that causes annoyance or anger deliberately is "provocative." This term is often used to refer to actions, statements, or behaviors that are intended to provoke a reaction or response from others, particularly in a manner that can elicit strong emotions such as anger or irritation. Provocative behaviors are typically calculated and meant to instigate a specific emotional response, making it clear that the intent behind them is to challenge, disturb, or upset.

Other terms listed have their own meanings but do not capture the deliberate intent as effectively. "Annoying" describes something that causes irritation but lacks the connotation of intentional provocation. "Inciting" refers to urging someone to take action, often in an aggressive way, but it doesn’t specifically denote causing annoyance or anger as its primary function. "Inflammatory" usually pertains to language or actions that incite strong feelings or civil unrest, focusing more on intense reactions rather than the purpose of annoyance. Thus, "provocative" is the most fitting choice as it embodies the deliberate intention to elicit a specific negative emotional response.
