[[An event nominalization word is a °word derived from a verb, denoting the °event.]]
The simpler "event nominalization" can also refer to the entire construction, including the arguments. For this, the fuller "event nominalization construction" can be used.
action nominal (a.k.a. nominalization) (STR) = a deranked predicate form that is capable of inflecting for case or of taking adpositions in the same way as nouns do, and with reasonable productivity. Example: in He remains under investigation, investigation is an action nominal. Action nominals overwhelmingly lack predicate-like tense–aspect– mood and argument indexation inflections.
