chilling

Synonym discussion
Sense: adjective/1
All four words describe something that causes fear, but they differ in intensity and tone. 'Frightening' is the broadest term — a loud noise, a dark room, or a threatening animal can all be frightening. 'Chilling' adds a specific quality of cold dread, often tied to violence or cruelty; a horror film can be frightening, but a true-crime documentary describing a murderer's actions is chilling. 'Terrifying' is stronger and suggests immediate, paralysing fear. 'Horrifying' focuses on shock and moral disgust — it is used for events that are not only scary but also deeply wrong. 'Hair-raising' is informal and can describe an exciting thrill, as in a roller-coaster ride or a ghost story around a campfire. For example: the roller-coaster was hair-raising (not chilling); the crime scene photos were horrifying (not just frightening); the dictator's final message to his family was deeply chilling.

Etymology
The adjective 'chilling' comes from the Old English verb 'cilian' meaning 'to become cold'. By the 1300s, 'chill' was used figuratively to describe a feeling of fear or dread, as fear was thought to make the body feel cold. The adjective 'chilling' in its frightening sense has been in use since the 1500s. The specialised legal sense — describing a 'chilling effect' on rights and freedoms — developed in 20th-century American constitutional law, first appearing in Supreme Court discussions about laws that discourage people from exercising their First Amendment rights.
