'unusually-connected' originates from the combination of 'unusual' and 'connected', where 'unusual' means 'not common' and 'connected' means 'joined or linked'.

'unusual' comes from the Latin word 'inusitatus', and 'connected' comes from the Latin word 'connectere'.

Initially, 'unusual' meant 'not in common use', and 'connected' meant 'joined together'. Over time, 'unusually-connected' evolved to describe relationships that are not typical.
