Helen Sword in NYTimes' Opinionator:
Take an adjective (implacable) or a verb (calibrate) or even another noun (crony) and add a suffix like ity, tion or ism. You’ve created a new noun: implacability, calibration, cronyism. Sounds impressive, right?
Nouns formed from other parts of speech are called nominalizations. Academics love them; so do lawyers, bureaucrats and business writers. I call them “zombie nouns” because they cannibalize active verbs, suck the lifeblood from adjectives and substitute abstract entities for human beings:
The proliferation of nominalizations in a discursive formation may be an indication of a tendency toward pomposity and abstraction.
The sentence above contains no fewer than seven nominalizations, each formed from a verb or an adjective. Yet it fails to tell us who is doing what.
