'misleadingly-altered' originates from the combination of 'misleadingly' and 'altered'. 'Misleadingly' comes from 'mislead', which originates from Old English 'mislædan', where 'mis-' meant 'wrongly' and 'lædan' meant 'to lead'. 'Altered' comes from Latin 'alterare', meaning 'to change'.

'misleadingly' evolved from 'mislead', which was used in Middle English as 'misleden'. 'Altered' was adopted from the Latin 'alterare' through Old French 'alterer'.

Initially, 'mislead' meant 'to lead astray', and 'alter' meant 'to change'. Over time, 'misleadingly-altered' evolved to mean 'changed in a deceptive way'.
