'anticipatively-formed' originates from the combination of 'anticipate' and 'form', where 'anticipate' comes from Latin 'anticipare', meaning 'to take before', and 'form' from Latin 'formare', meaning 'to shape'.

'anticipate' changed from the Latin word 'anticipare' and 'form' from 'formare', eventually combining in modern English to form 'anticipatively-formed'.

Initially, 'anticipate' meant 'to take before', and 'form' meant 'to shape'. Together, they evolved to mean 'created in anticipation of future needs'.
