Greetings to you too! "Let go" and "let's go" are two different phrases with distinct meanings: Let go: This phrase means to release or relinquish one's hold on something or someone. It can be used literally, such as when you're holding onto an object and you release it. However, it's often used figuratively to refer to releasing emotional attachments, grudges, or control over a situation. For example, "It's time to let go of the past and move forward." Let's go: This is a contraction of "let us go." It's an invitation or suggestion to start an activity, move to another location, or begin an action together with someone else. For instance, if you're suggesting that you and a friend should leave for a trip, you might say, "Let's go on an adventure!" In summary, "let go" is about releasing something or someone, either physically or emotionally, while "let's go" is an invitation or suggestion to start an activity or move together with someone.

Grammatically, the difference is that in the first phrase the verb has no direct object whereas in the second phrase, "us" is the direct object. "Let go" means "allow to go", or to release. As a command, "Let go!", it means "Release!". With a subject such as "He let go" it means "he released". "Let us go" means the same but specifies that the thing released is "us". Spoken to someone else (who is not part of "us") it means "allow us to depart". Spoken among ourselves, it means "Let us get going!".

"Let go" means "Release" "Let's go" means "Let us go," "Let us travel somewhere," etc. I hope this helps.
