'waveringly-aimed' originates from the combination of 'waveringly' and 'aimed'. 'Waveringly' comes from the verb 'waver', which originates from Middle English 'waveren', meaning 'to sway or flutter'. 'Aimed' is the past participle of 'aim', which comes from Old French 'esmer', meaning 'to estimate or intend'.

'waveringly' evolved from the verb 'waver', which was used in Middle English as 'waveren'. 'Aimed' evolved from the Old French 'esmer', which was adapted into Middle English as 'aimen'.

Initially, 'waver' meant 'to sway or flutter', and 'aim' meant 'to estimate or intend'. Over time, 'waveringly-aimed' came to describe something directed with uncertainty.
