What does underway mean?
Underway means that something is already in progress or actively moving forward. It is commonly used for projects, investigations, discussions, and other activities that have begun but are not complete: "The renovation is well underway." The word can also describe a ship, vehicle, or journey that is in motion. It conveys not merely that something has started, but often that it is progressing with momentum. Underway belongs to both adjective and adverb categories, although its predicative use is frequently treated simply as adjectival. The expression is common in British and American English, while "under way" remains a traditional spelling variant. Underway is useful because it distinguishes active development from a plan that has not yet started or an undertaking that has stopped. It also suggests forward movement and continuing engagement, making it more vivid than simply "begun" and more specific than the broad "happening."
In progress or already happening and moving forward.
"The investigation is underway."
Usually used predicatively, though attributive uses such as "underway efforts" also occur.
In a state of active progress or forward movement.
"The negotiations are already underway."
The adverb form is closely tied to predicative use and is often interchangeable with the adjective in modern usage.
Underway began as a nautical expression for a ship making way under sail before becoming a general description of anything actively progressing.

Where does underway come from?
Underway developed from the expression "under way," combining the preposition "under" with "way" in the language of movement and navigation. The phrase was originally associated with a vessel making progress under sail and was later generalized to describe activities in progress. Its modern figurative meaning is now more common than the literal nautical sense.
How underway is actually used
Underway is neutral in register and is especially common for work, projects, investigations, discussions, and other activities in active progress. It is frequently used predicatively, as in "the work is underway."
