'insufficiently-related' originates from the combination of 'insufficiently' and 'related'. 'Insufficiently' comes from Latin 'insufficientem', where 'in-' meant 'not' and 'sufficientem' meant 'adequate'. 'Related' comes from Latin 'relatus', where 're-' meant 'again' and 'latus' meant 'carried'.

'Insufficiently' evolved from the Latin 'insufficientem' through Old French 'insuffisant', and 'related' evolved from Latin 'relatus' through Old French 'relater'.

Initially, 'insufficiently' meant 'not enough', and 'related' meant 'carried back'. Over time, they combined to describe a lack of adequate connection.
