'mixture' originates from Latin, specifically the word 'mixtura', where 'mixt-' came from 'mixtus' meaning 'mixed' (past participle of 'miscere', to mix).

'mixture' changed from Latin 'mixtura' into Old French 'mixture' (or similar forms) and then entered Middle English as 'mixtur' / 'mixture', eventually becoming the modern English word 'mixture'.

Initially, it meant 'the act of mixing' or 'that which is mixed', and over time it evolved into the general modern sense of 'a combination of different things' (both literal and figurative).
