功能多样性：非限定动词的结构 Functional Diversity: The Anatomy of Non-Finites

非限定动词，也称为动词性词语 (Verbals)，是动词的形式，它们不带有传统的时态和人称屈折。由于缺少这些必要的屈折变化，它们不能充当标准限定子句的主谓语 (Main Predicate)。非限定动词对于锚定复杂的、可移动的短语至关重要。这些短语——不定式、动名词和分词——随后在句子中主要充当名词、形容词或副词。其决定性特征是它们不能显示动作发生的时间或执行者，这迫使它们处于从属地位。 Non-finite verbs, also known as Verbals, are forms of the verb that do not carry the traditional Tense and Person Inflection. Because they lack these necessary inflections, they cannot function as the Main Predicate of a standard finite clause. Non-finite verbs are essential for anchoring complex, mobile phrases. These phrases—the Infinitive, the Gerund, and the Participle—then function within the sentence primarily as nouns, adjectives, or adverbs. The defining characteristic is their inability to show when an action occurred or who performed it, forcing them into subordinate roles.
