in-progress

The compound adjective "in-progress" is a modern English formation, directly combining the native preposition "in" with the Latinate noun "progress." The logic is transparent: something is literally "in a state of forward movement." The word "progress" itself has a rich history, stemming from Latin 'progredi', where 'pro-' signifies forward direction and 'gradi' denotes stepping or walking, a concept traceable to the Proto-Indo-European root ghredh- ("to walk, go"). Over centuries, "progress" evolved from a literal physical advancement to an abstract concept of development or improvement. The hyphenated form "in-progress" emerged in the 20th century, primarily in administrative and technical contexts, to neatly label tasks or projects actively underway, perfectly encapsulating the idea of being within the ongoing process of forward movement.
