英语语法概念： Deverbal noun
Deverbal nouns are nouns that are derived from verbs or verb phrases, but that behave grammatically purely as nouns, not as verbs. They are distinct from verbal noun types such as gerunds and infinitives, which behave like verbs within their phrase (although that verb phrase is then used as a noun phrase within the larger sentence).
