'occasionally-recorded' originates from the combination of 'occasionally,' meaning 'at irregular intervals,' and 'recorded,' meaning 'documented or noted.'

The term 'occasionally' comes from the Latin word 'occasionalis,' and 'recorded' comes from the Latin 'recordari,' meaning 'to remember.'

Initially, 'occasionally' meant 'pertaining to an occasion,' and 'recorded' meant 'to remember or recall.' Over time, it evolved to mean 'documented at irregular intervals.'
