'appendicle' originates from Late Latin, specifically the word 'appendicula', where 'ad-/ap-' meant 'to' and 'pendere' meant 'to hang'.

'appendicle' changed from the Late Latin word 'appendicula' (a diminutive of 'appendix') through Medieval Latin and Middle English forms and eventually became the modern English word 'appendicle'.

Initially, it meant 'a small hanging thing' (a diminutive of an attached or hanging part), but over time it evolved into its current meaning of 'a small appendage or outgrowth'.
