'irregularly-connected' originates from the combination of 'irregularly' and 'connected', where 'irregularly' is derived from Latin 'irregularis', meaning 'not regular', and 'connected' from Latin 'connectere', meaning 'to bind together'.

'irregularis' transformed into the Old French word 'irregulier', and eventually became the modern English word 'irregular'. 'Connectere' transformed into the Old French word 'connecter', and eventually became the modern English word 'connect'.

Initially, 'irregularly' meant 'not regular', and 'connected' meant 'joined together'. Over time, 'irregularly-connected' evolved to describe something not consistently linked.
