Etymology
'non-bidirectional' originates from English, formed by the prefix 'non-' (meaning 'not') attached to 'bidirectional', where 'bidirectional' itself comes from 'bi-' (two) + 'directional' (related to 'direction').
'bidirectional' derives from Latin/Old French elements: Latin 'bi-' meaning 'two' combined with 'direction' (from Latin 'directio' meaning 'a guiding, straightening'). The adjective 'bidirectional' was formed in modern English; 'non-' (from Latin 'non') was then prefixed to create 'non-bidirectional.'
Initially, 'bidirectional' meant 'having or permitting movement/operation in two directions'; 'non-bidirectional' was formed to express the opposite—'not two-way' or 'one-way'—and this oppositional meaning is its current usage.
