Etymology
Origin of inform1
First recorded in 1350–1400; Middle English enfo(u)rmen, informen, from Old French enfo(u)rmer, from Latin infōrmāre “to form, shape,” equivalent to in- in- 2 + fōrmāre “to form ”
Origin of inform2
First recorded in 1545–55; from Latin informis “formless, deformed,” equivalent to in- in- 3 + -formis -form
Explanation
To inform is to tell someone news, pass on wisdom, leak gossip, or give instruction. You've been informed that you won the raffle at the county fair. What are you going to do with all that cheese? The Latin verb infōrmāre means "to form or shape." The idea of passing on knowledge came about in the 14th Century, with the meaning of "teaching or instructing" coming later. Thomas Jefferson, who believed democracy to be impossible without informed citizens, said, “Educate and inform the whole mass of the people... They are the only sure reliance for the preservation of our liberty.”
