# Create A List Of Atoms The `~w` sigil makes it easy to create a word list -- a list of strings -- where each word is separated by a space. ```elixir > ~w(bulbasaur charmander squirtle) ["bulbasaur", "charmander", "squirtle"] ``` By appending an `a` onto that sigil construct, you are instructing Elixir that you would instead like a list of atoms. ```elixir > ~w(bulbasaur charmander squirtle)a [:bulbasaur, :charmander, :squirtle] ``` [source](http://elixir-lang.org/getting-started/sigils.html#strings)
