What does terminal mean?
Terminal describes something that comes at an end, forms an endpoint, or is the final stage of a process. It is used for practical endpoints such as terminal stations and computer terminals, for the final and most advanced phase of a process, and—most importantly in everyday medical usage—for an illness that will lead to death. The adjective often has a serious or conclusive tone, while the noun can refer to a building, installation, or device where a journey or system ends. As a verb, terminal is formal but clear: it means to bring something to an end. The word's range reflects its Latin roots in ideas of boundaries and limits. In modern English, terminal can therefore connect physical endpoints, technical systems, decisive final stages, and the ultimate limit of life.
Forming or situated at an end; serving as a final stage or endpoint. In medical contexts, leading to death; final or ultimate.
"The terminal report explained that no further treatment could reverse the condition."
The medical sense is formal and commonly used with words such as illness, condition, and cancer.
An endpoint or device used to enter data into, or receive information from, a computer. It may also refer to a building or area where passengers arrive or depart in a transport system.
"Passengers waited in the main terminal until their connecting flight began boarding."
The computing sense is established technical vocabulary, while the transport sense is common in British and American English.
To bring something to an end or cause it to come to an end.
"The agreement was terminal and both teams left the field without another dispute."
This is a formal usage and is less common than end or terminate in everyday speech.
The plural is used for computer devices, transport endpoints, and other distinct end points or installations.
"All terminals were closed for scheduled maintenance during the night."
From the Latin terminus, meaning a boundary or limit, terminal grew to describe everything from the end of a journey to the final stage of life.

Where does terminal come from?
Terminal comes through French terminal from Latin terminalis, meaning “of or belonging to an end.” It derives from Latin terminus, a boundary or limit, related to the verb terminare, “to end.” The same Latin root produced English words including terminate, terminology, and term, and the Roman road was called a terminus, giving the word its associations with both endpoints and travel.
