This year's 'Word of the Year'.... isn't a word.

FOX's Rich Denison explains:

For 2015, an 'ism' is in. The tiny suffix ism named by Merriam-Webster as the Word of the Year, as it is included in the ranks among the top look-ups of words on the organization's website. The year saw a spike in searches for ism-ending words, including socialism, fascism, feminism, capitalism and terrorism.

It was also aided by searches for federalism, Marxism, masochism and professionalism.

Over at Oxford Dictionaries, an emoji of a face with tears of joy was tapped for 2015's top word.

Dictionary.com did go with a word for word of the year, which was "identity."
