Etymology

The word combines the preposition "in," denoting location or state, with "service," derived from Old French servise (duty, labor), itself from Latin servitium (slavery, servitude). Over time, "service" broadened to mean organized work or assistance. "In-service" emerged in the 19th century, primarily describing activities (e.g., training) conducted while actively employed, contrasting with preparatory or external education. The morphemes retain their original spellings, reflecting a transparent compound structure.
