Let's go, in essence, refers to a complete statement, where the verb "let" is used as an instrumental subject and accompanied by the auxiliary verb "be." In this case, when "let's go" is put back together with the preposition "and," it becomes "let us go," making it a simple imperative phrase expressing a command or request.
Yes, the construction of the sentence "Let's go" in English can be classified as an imperative sentence, which is one of the five basic types of sentences commonly found in the English language:
-
Imperative: This type of sentence expresses a command or a request that should be followed or taken into action immediately. Example: "Go to the store."
-
Personal: An imperative sentence typically has the first person singular form of the verb (e.g., "She goes to the store.") to indicate who is giving the order. Example: "Alice goes to the store."
-
Impersonal: An imperative sentence can also have a third person singular form of the verb, but the focus is on the subject rather than specifying a specific person. Example: "We all go to the store."
-
Interrogative: An imperative sentence usually starts with the auxiliary verb "do" (e.g., "Do you go to the store?"). Example: "Are you going to the store?"
-
Imperative with Future Tense: A conditional imperative sentence can have the future tense form of the verb "will" or "shall" (e.g., "Will you go to the store tomorrow?"). Example: "If I go to the store tomorrow, I will buy some snacks."
In the given context, let's go can be considered an imperative sentence because it follows the structure of a simple imperative phrase with a command or request. The sentence requests the reader or listener to proceed with their intended action, potentially towards going to a store.
