“落”在粤方言中是一个被广泛使用的动词。经过考察，“落”主要在短语和句子中扮演谓语和补语的角色。做谓语的“落”在动宾结构中搭配宾语；做补语的“落”则在述补结构中对述语进行补充说明。 粤方言动词“落”的语法功能与普通话动词“下”大体类似：二者都可充当谓语、补语，有大量相同的可搭配宾语、做补语时对述语的补充说明功能也高度一致。 经过与“下”的比较发现，粤方言“落”确实在语法功能上体现出一定特点。譬如，粤方言“落+NP”在一定条件下会出现的歧义现象，而普通话“下+NP”并不存在此种现象；粤方言“落+处所宾语”和普通话“下+处所宾语”动宾结合的紧密程度有所不同，因而插入趋向补语的位置也有所区别，等等。简而言之，粤方言“落”从能够做谓语、补语的角度看是一个与普通话“下”大体类似的动词，但在具体细微的层面，其语法功能又表现出自身特点。

Lok(落) is a widely used verb in Cantonese dialect. It can function as predicate and complement in phrases and sentences. As a predicate, Lok is used to match an object to form a verb-object structure, while as a complement, it isattached to predicates in predicate-complement structures. The grammatical function ofLok is similar to that of the Mandarin verb Xia(下). Both of the two verbs can act as predicate and complement, sharing a large amount of objects, and high level of similarity in making complement. It can be found that Lok does show certain characteristics in comparison with Xia. For example, Lok+NP phrases in Cantonese dialect are expected to show ambiguity under certain conditions, while this kind of phenomenon doesn’t exist in Xia+NP phrases in Mandarin. Also, the relationship between Lok/Xia and their objectsin combination is different, which influences how directional complements are inserted, and so on. In short, Lok is resembled to the Mandarin verb Xia from the perspective of being predicate and complement, but still has its own characteristics in a practical level.
