Addiction: Is a relatively recent word, at least in its current usage. It has only been used to relate to a chemical dependence since 1910, previously it meant ‘devotion’. It has its roots in the Latin word ‘addictus’ which meant in a literal sense ‘to sell’ or ‘award’ – essentially to give over. It was also used by the Romans to mean to give over in a metaphorical sense, such as to sacrifice.
The word ‘Addictus’ comes from combining ‘ad’ meaning to, and ‘dicere’, meaning ‘declare’.
