not having a direction

Etymology
Etymology Information

'nondirectional' originates from English, specifically the prefix 'non-' meaning 'not' and the adjective 'directional' (from 'direction' + suffix '-al').

Historical Evolution

'directional' comes from the noun 'direction', which derives from Latin 'directio' (from 'dirigere' meaning 'to direct'). The negative form 'non-' has been used in English to form adjectives meaning 'not X', producing 'nondirectional' as 'not directional'.

Meaning Changes

Initially formed by combining 'non-' + 'directional' to mean 'not directional'; it has retained that basic negative meaning while also acquiring technical senses (e.g., 'not favoring any direction').
