Origin of 'unreactive'

The term 'unreactive' originated from the prefix 'un-' meaning 'not' and the adjective 'reactive', which stems from the Latin word 'reactivus' and the verb 'reagere', meaning 'to act again'. The concept of reactivity in chemistry has been studied extensively to understand the behavior of substances and their interactions.
