What does hotline mean?
A hotline is a telephone line or service intended for urgent communication. It is commonly used for emergency services, crisis support, customer assistance, and public-information lines, as in “emergency hotline” or “toll-free hotline.” The word can also describe any direct communication channel kept open for rapid contact, including one used by government agencies, businesses, or emergency teams. In everyday usage, a hotline conveys immediacy and access: it suggests that someone can reach assistance quickly rather than wait through a general telephone queue. Although the term has a practical, institutional feel, it is also used metaphorically for other priority channels, such as a direct line for communication between departments. Its modern meaning grew out of the older sense of a specially designated telephone line for urgent or confidential conversations.
A telephone line or service reserved for urgent, emergency, confidential, or priority communication.
"The local authority opened a hotline to help people affected by the flooding."
Commonly used with modifiers such as “emergency,” “crisis,” “information,” “toll-free,” and “customer.” It may also refer to a direct communication channel rather than a literal telephone line.
To communicate with someone or some organization through a hotline, especially for urgent or direct contact.
"Residents could hotline the council for instructions about the evacuation."
The verbal use is relatively uncommon and is more typical of institutional, technical, or organizational contexts than of ordinary conversation.
The plural is used when referring to multiple telephone services or communication channels.
"Several emergency hotlines remained operating throughout the night."
A hotline is a phone line for moments when waiting feels like the wrong answer.

Where does hotline come from?
The word combines the English words “hot” and “line.” Its modern telephone sense developed during the early 20th century, when a “hot line” could mean a connection intended for especially immediate or urgent business. Over time, the compound was standardized as the single word “hotline,” and its use expanded to include emergency, public-information, and customer-service telephone lines.
