“Elucidate” can be traced back to the Latin “lucidus,” which means “to shine.” When you elucidate something, you shine light on its meaning. Teachers are the best source of elucidation for many people around the world. The United Nations estimates that to provide every child in the world with quality education would require training nearly 70 million more teachers. The U.N. has made it a goal to give every child the education they deserve by 2030. That’s a goal worth shining a light on.
