'entwine' originates from Old English, specifically the form 'intwīnan' (or 'entwinen'), where the prefix 'in-/en-' meant 'in/into' and 'twine' derived from Old English 'twīnan' meaning 'to twist'.

'entwine' changed from Old English 'intwīnan' to Middle English 'entwinen' and eventually became the modern English 'entwine' (with present participle 'entwining').

Initially, it meant 'to twist together or around', and over time it has retained this core sense of 'twisting, winding, or interweaving' though it is also used figuratively (e.g., to entwine lives or stories).
