'accessory-bearing' originates from English, specifically the words 'accessory' and 'bearing', where 'accessory' comes from Latin 'accessorius' meaning 'additional/related to an approach' and 'bearing' comes from Old English 'beran' meaning 'to carry'.

'accessory' changed from Latin 'accessorius' to Old French (e.g. 'accesorie') and then Middle English 'accessorie', eventually becoming modern English 'accessory'. 'Bearing' derives from Old English 'beran' → Middle English 'beren' with the gerund/participle suffix '-ing' forming 'bearing'. These components were later combined in English to form the compound 'accessory-bearing'.

Initially, the elements meant 'additional/related' (accessory) and 'to carry' (bearing); over time the compound evolved to mean 'having or carrying accessories' in contemporary usage.
