Ido
Each word in Ido comes from a smaller word called a root word. A root word has a root and an ending. The speaker can take the root and put it on another word to make a new one. For example, urbo means "city" and -estro means "leader". The root of urbo is urb-, and if -estro is put on the end, it becomes urbestro, which means mayor (leader of a city). Or the speaker can put something on before; chef- means chief or leader, and if the speaker puts that before the word it becomes chefurbo, which means capital city.
