The "word" that leaps unbidden into my mind is
incentivation. This ungainly portmanteau of
incentive and
motivation was coined in 1987 by Australia's Liberal Party, and helped scuttle John Howard's first attempt to be elected as Prime Minister.
As mentioned in the links you provide, anonsi,
incent has been included in some dictionaries, and it is being used by some people, though others are aghast. Looking in a few newspaper archives, the word seems to appear mostly in quotes, rather than being used by staff writers. I can imagine that some journalistic style guides might proscribe it.
One example is from a
Guardian article shortly after the 2008 US presidential election, where heads of various environmental organisations were asked what advice they would give to President-Elect Obama. A Terry Kellogg advised:
You should incent companies to show what a new, truly sustainable paradigm looks like.
Has the president followed this advice? I've no idea.
Fortunately, I don't have to determine which words
should be in the language, only which words
are in the language. Evidently
incent has carved out a little niche for itself, and should be accepted in puzzles.
