A caller from Burlington, Vermont, has observed a slight change in the language of flight attendants’ instructions, replacing your with that. Instead of saying “Put your coat in the overhead compartment,” the ones on the airline she frequents say, “Put that coat in the overhead compartment.” Linguistic anthropologist Barbara Clark has analyzed the scripted language of flight attendants and finds their deferential speech is calculated in part to gain the respect and loyalty of passengers. This is part of a complete episode.
