'habitually-carried' originates from the combination of 'habitually' and 'carried'. 'Habitually' comes from the Latin word 'habitualis', meaning 'customary', and 'carried' is the past participle of 'carry', which comes from the Old French 'carier', meaning 'to transport'.

'habitualis' transformed into the Old French 'habituel', and eventually became the modern English word 'habitual'. 'Carier' transformed into the Middle English 'carien', and eventually became the modern English word 'carry'.

Initially, 'habitual' meant 'customary or usual', and 'carry' meant 'to transport'. The combined term 'habitually-carried' retains the meaning of being regularly transported.
