playing is a type of transitive verb in the English language, which is used to express actions or states. In English, verbs can be broadly categorized into two main types based on their function and usage: predicate verbs and non-predicate verbs. In Chinese grammar, verbs that indicate actions or dynamic changes of people or things usually appear after the subject noun or in the main sentence. Additionally, verbs in English also undergo tense changes. As for the transitive verbs, they specifically indicate actions, existence, or mental activities. Among them, there is a type of directional verb that can function as a predicate on its own, such as “The moon went down, but the sun has not risen yet.” These verbs are also frequently used after other verbs or adjectives to indicate a tendency, serving as a directional complement.
