  • A unit of physical activity used in time-and-motion studies in industrial engineering; each therblig represents one of 18 standardized activities identified by the American industrial psychologists Frank B. Gilbreth and Lillian M. Gilbreth: search, find, select, grasp, hold, position, assemble, use, disassemble, inspect, transport loaded, transport unloaded, preposition for next operation, release load, unavoidable delay, avoidable delay, plan, and rest for overcoming fatigue. The word is a backward spelling (counting "th" as one letter) of Gilbreth.

  • This is a great word! It is a unit of time in terms of "time and motion" studies, which isn't so great. What's great about it is that its Gilbreth spelled backwards. The Gilbreths (husband and wife) were pioneers in the wretched matter of industrial time and motion study. Wonderful way to sneek into the dictionary!
