'inconsistently-recorded' originates from the combination of 'inconsistent' and 'recorded'. 'Inconsistent' comes from Latin 'inconsistens', where 'in-' meant 'not' and 'consistens' meant 'standing firm'. 'Recorded' comes from Latin 'recordari', where 're-' meant 'again' and 'cordis' meant 'heart'.

'Inconsistently-recorded' evolved from the combination of 'inconsistent' and 'recorded', which were used separately in Middle English and later combined in modern English.

Initially, 'inconsistent' meant 'not standing firm', and 'recorded' meant 'to remember'. Over time, they combined to describe something documented without regularity.
