In linguistics, a libfix is a productive bound morpheme affix created by rebracketing and back-formation, often a generalization of a component of a blended or portmanteau word. For example, walkathon was coined in 1932 as a blend of walk and marathon,[1] and soon thereafter the -athon part was reinterpreted as a libfix morpheme meaning "event or activity lasting a long time or involving a great deal of something".[2][3] Words formed with this suffix include talkathon, telethon, hackathon, and so on. Affixes whose morpheme boundaries are etymologically based, and which are used in their original sense, are not libfixes. Libfixes often utilise interthesis, as in the example of -holism and -holic which are joined with consonant-final segments via the vowel /a/, creating work-a-holism or sex-a-holism.


Splinters were defined by Berman in 1961 as non-morphemic word fragments. This includes not just libfixes, but also word fragments which become words, like burger (< hamburger), flu (< influenza), and net (< network).[4][5][6]

The name libfix was coined by Arnold Zwicky in 2010 as a blend of "liberated" and "affix" specifically for splinters used as productive morphemes.[7]


Some of these formations have been considered barbarisms by prescriptive writers on style,[8] though other writers have praised them. Speaking of the -tron suffix, a philologist commented:

I once heard an unkind critic allude disparagingly to these neologisms as dog-Greek. To a lover of the language of Sophocles and Plato these recent coinages may indeed appear to be Greek debased. More appropriately, perhaps, they might be termed lion-Greek or chameleon-Greek. They are Neo-Hellenic in the genuine Renaissance tradition.[9]


Each example gives the affix, the source word(s) from which it was formed, the meaning, and examples.
