/ˌnɒn.aɪˈsɒməfi/
not the same structure / absence of isomorphism
Etymology
'nonisomorphy' originates from Modern English formation by prefixing 'non-' to 'isomorphy', where 'non-' meant 'not' and 'isomorphy' traces to New Latin/Greek elements 'iso-' ('equal') and 'morphē' ('form, shape').
'isomorphy' comes from New Latin 'isomorphia', ultimately from Greek 'isomorphos' (from 'isos' + 'morphē'); English adopted 'isomorphy' and then formed 'nonisomorphy' by adding the negative prefix 'non-'.
Initially, the root meant 'having the same form' (isomorphy); over time 'nonisomorphy' has been used in technical contexts to mean 'not having the same form' or 'absence of isomorphism', which is its current mathematical sense.
