In an early post I noted the existence of libfix-like elements where the newly liberated affix mirrors existing—though possibly semantically opaque—morphological boundaries. The example I gave was that of -giving, as in Spanksgiving and Friendsgiving. Clearly, this comes from Thanksgiving, which is etymologically (if not also synchronically) a compound of the plural noun Thanks and the gerund/progressive giving. It seems some morphological innovation has occurred because this gives rise to new coinages and the semantics of -giving is more circumscribed than the free stem giving: it necessarily refers to a harvest-time holiday, not merely to “giving”.
At the time I speculated that it was no accident that the morphological boundaries of the new libfix mimic those of the compound. Other examples I have since collected include –mare (< nightmare; e.g., writemare, editmare); –core (< hardcore; e.g., nerdcore, speedcore) and –step (< two-step; e.g., breakstep, dubstep), both of which refer to musical genres (Zimmer & Carson 2012); –gate (< Watergate; e.g., Climategate, Nipplegate, Troopergate) and –stock (< Woodstock; e.g., Madstock, Calstock), extracted from familiar toponyms, and –position (< exposition; e.g., sexposition, craposition), for which the most likely source can be analyzed as a Latinate “level 1” prefix attached to a bound stem. So, what do we think? Are these libfixes too? Does it matter that recutting mirrors the etymological—or even synchronic—segmentation of the source word?
