'irregularly-linked' originates from the combination of 'irregularly' and 'linked', where 'irregularly' is derived from Latin 'irregularis', meaning 'not regular', and 'linked' from Old English 'hlencan', meaning 'to join or connect'.

'irregularly' evolved from the Latin 'irregularis', and 'linked' from the Old English 'hlencan', eventually forming the modern English term 'irregularly-linked'.

Initially, 'irregularly' meant 'not regular', and 'linked' meant 'joined', which together evolved to describe something connected in a non-uniform manner.
