Etymology: "Timeframe" is simply the closed-up spelling of "time frame," a compound of two very old English words. "Time" comes from Old English "tīma," and "frame" from Old English "framian," meaning to be useful or to make progress, later coming to mean to construct or shape something. The frame sense, a structure that holds or shapes something, developed from that older idea of making or fitting together. Put together, a time frame is a frame placed around a stretch of time, marking its boundaries so that events can be fitted inside. The image is a literal one: the period is treated like a picture or window that contains what happens within it. The spelling as one word is the newer form, and the two-word version remains the more common in formal writing.

Synonyms: period, duration, timespan, timeline, schedule
