holus-bolus

The story of holus-bolus is not a hard one to swallow. Holus-bolus originated in English dialect in the mid-19th century and is believed to be a waggish reduplication of the word bolus. Bolus is from the Greek word bōlos, meaning "lump," and has retained that Greek meaning. In English, bolus has additionally come to mean "a large pill," "a mass of chewed food," or "a dose of a drug given intravenously." Considering this "lumpish" history, it's not hard to see how holus-bolus, a word meaning "all at once" or "all in a lump," came about.
