The word came from linotype typesetting machines. The first, left row of six keys on a linotype machine produce the word "etaoin". The second, left row of six keys produce the word "shrdlu". The linotype machine keys are labeled: "etaoin-shrdlu-cmfgyp-wbvkxj-qz". The letter 'h' appears more often in every day speech and writing than it does in a list of dictionary words.
