The origin is estimated to be around 1575-85. In Latin, lētālis, is equivalent to lēt ( um ) death + -ālis -al1 ; spelling (hence pronunciation) with -h- . It also has an association with Greek lḗthē meaning oblivion. Deadly and lethal mean the same thing. The lethal mixture of chemicals could kill a human within hours. Deadly force can only be used in particular circumstances by law. It would be redundant - repetitive and grammatically incorrect - to use "deadly and lethal" in the same sentence. Pick and use only one or use your own original wording. Though many people use the expression, "It killed me!" they do not mean 'it' was either deadly or lethal. Obviously the person is alive or could not speak that trite phrase. "Deadly force" has become a trite phrase. Often it is unnecessary to state "deadly" or "lethal" in writing. For example, this sentence contains redundancy that is unnecessary. "The deadly bullet exploded in the man's heart." Obviously, (1) bullets can be deadly (2) if it exploded in the man's heart then it was obviously death-dealing or deadly. Chemists, Medicine/Nursing, law enforcement (and of course criminals) are most apt to concern themselves with "lethal doses" of chemicals or drugs.
