Etymology

while = wh<time> + ile<noun suffix>

  • wh (from Old English hwīl "time, period")
  • ile (a nominal suffix in Old English, indicating a state or condition)

Etymology Origin:
The word "while" traces back to Old English hwīl, meaning "a period of time." It shares roots with German Weile and Dutch wijl, all derived from Proto-Germanic hwīlō. The original sense of "time" evolved into its modern conjunction usage ("during the time that") and the noun meaning ("a period"). The verb form, now archaic, once meant "to spend time idly." The morpheme wh preserves the core idea of time, while -ile acts as a nominalizer.
