Is it right to say no colon here "I will give him the boot from the company no full stop here" or "I will get him the boot from the company no full stop here"?
Note my corrections above. There was no need for a colon. Don't put a space after opening quotation marks. Don't use a full stop at the end of a quoted sentence if the surrounding sentence continues after the closing quotation marks.
"I will give him the boot" could be said only by someone with the ability to fire someone.
"I will get him the boot" could be said by someone who is going to arrange for someone else to be fired.
In what context do you want to say these sentences?
