'preemptively-formed' originates from the combination of 'preemptive' and 'formed'. 'Preemptive' comes from Latin 'praeemptio', meaning 'buying beforehand', and 'formed' from Latin 'formare', meaning 'to shape'.

'Preemptively-formed' evolved from the concept of 'preemptive action' in strategic contexts, combined with 'formed' to describe something created in advance.

Initially, 'preemptive' meant 'buying beforehand', but over time it evolved to mean 'acting in advance to prevent something'.
