What does offline mean?
Offline describes a state in which someone or something is not connected to the internet, a network, or an online service, and it can also mean that something cannot be accessed online. The word is used in practical digital contexts, such as saving a document for offline use, switching a device into offline mode, or continuing to work without a connection. It may describe the absence of a network connection itself, as in 'the computer went offline,' or a lack of online access, as in 'offline maps.' Offline can also carry a broader social meaning: an offline meeting or discussion is one that takes place in person rather than through the internet. The related adjective use is especially common in computing, where it distinguishes local or network-independent operation from online functionality.
While not connected to the internet or another network, or while an online service is unavailable.
"The device automatically saves changes offline when it loses its connection."
This is the most established use. In technical contexts, it often contrasts with online.
Not connected to the internet or another network, or not available through an online service.
"The app includes an offline version of the dictionary."
Common in digital and technical contexts, especially with mode, access, version, and storage.
Offline is more than simply being disconnected: it describes a whole state in which the internet, network resources, or online services are unavailable.

Where does offline come from?
Offline is a modern compound of off and line, combining the sense of being apart or away from with line in the older meaning of a communication or network route. Its use expanded with networked computing to describe devices, users, documents, and services that are not connected to the internet. The component lineage is shared with words such as line, linear, and offing, although offline itself is a relatively recent formation.
How offline is actually used
The adverb is the traditional and most common use. As an adjective, it is common in technical and everyday digital contexts, as in 'offline mode' and 'offline access.' It is also used figuratively for activities or discussions conducted away from the internet.
