'uncertainly-directed' originates from the combination of 'uncertainly' and 'directed'. 'Uncertainly' comes from 'uncertain', which is derived from Latin 'incertus', meaning 'not sure'. 'Directed' comes from Latin 'directus', meaning 'straight' or 'guided'.

'uncertainly' evolved from Middle English 'uncertain', and 'directed' from Middle English 'directen', eventually forming the modern English compound adjective 'uncertainly-directed'.

Initially, 'uncertainly' meant 'not sure', and 'directed' meant 'guided'. Together, they evolved to describe something lacking clear direction.
