The root in the word admit is from the <em>Latin: </em><em>mittere</em><em> </em>, which means 'let go, send'. There are other words that come from this same root that reinforce this meaning (to release, let go;send, throw); one of them is mission: sending abroad an agent/embassy/body of persons etc. Other words are: missionary, commissioned, dismissal.
