'occasionally-connected' originates from the combination of 'occasionally,' derived from the Latin 'occasio,' meaning 'a happening or occurrence,' and 'connected,' from the Latin 'connectere,' meaning 'to bind together.'

'occasionally' evolved from the Latin 'occasio' through Old French 'occasion,' while 'connected' evolved from the Latin 'connectere' through Middle English 'connecten.'

Initially, 'occasionally' meant 'a happening,' and 'connected' meant 'to bind together.' Over time, 'occasionally-connected' evolved to describe something linked at irregular intervals.
