(Warning: moderately technical linguistics ahead — tailored for the non-specialist, but unsparing with crucial concepts and their accompanying terminology.)
Watching aimless tv recently, I came across this example, from NCIS: New Orleans, Season 6 Episode 16:
Hardin doesn’t have a criminal record, but he has been scandal-adjacent more than once. (from the transcript)
It was the Adj scandal-adjacent (of the form N + Adj) that caught my eye: literally ‘adjacent to scandal’, but here in an extended sense, roughly ‘(closely) associated with scandal’, suggesting that the association is uncomfortably close.
I then discovered that scandal-adjacent (sometimes spelled scandal adjacent) was reasonably common, and fraud-adjacent was too. And recalled a posting of mine on an extraordinarily euphemistic occurrence of adult adjacent with adult referring to sex.
It turns out that the compound Adj pattern X-adjacent ‘adjacent to X’ is an open one, with a variety of examples in OED3 (Dec. 2011). Except that OED3 incorrectly characterizes the pattern as involving postmodification rather than compounding.
