'nontransportability' originates from English, specifically formed from the prefix 'non-' + the verb 'transport' + the suffix '-ability', where 'non-' meant 'not' and '-ability' meant 'capability or fitness'.

'transport' originates from Latin 'transportare' (from 'trans-' meaning 'across' + 'portare' meaning 'to carry'), passed into Old French as 'transporter' and into Middle English as 'transport', and was later combined with English prefix 'non-' and suffix '-ability' to form 'nontransportability'.

Initially 'transport' meant 'to carry across', and over time the derived noun composed with 'non-' and '-ability' came to mean 'the state or quality of not being able to be carried across' (i.e., not able to be transported).
