Off
Off you go:
The more conventional word order for the command would be "you go off" (or "go off"), meaning "go away", but the word order "off you go" is more idiomatic. 'Off you go' means you can leave now. Usage : If you want someone to go away or go home, especially a kid but not in a rude way like 'get lost'.
"off" means "away from the position you are". In this case we are using inversion. When you have an adverb of place like "off" "there" "here" "out", you can use the inversion, for instance "There you go" "Here I am" "Out they went" etc.
- Off you go, I don´t want to see you now, go home.
- Are you ready? Off we go.
"Off" is the indication that the action of the verb will be in a direction that is away from person or thing upon which the verb acts.
The verb "to go" is a pure intransitive verb -> the verb acts on the subject.
(i)"Off you go" and (ii) "Off we go" are both the polite and friendly forms of the imperative.
(i) "Go away!" (off from this place/this situation.)" We do not say "Go off!"
and
(ii) "Let's go!" (Go away from this place/situation.) -> Often used to mean "Let's start [doing what we should be doing.]"
