meddle
Pronunciation: /ˈmɛd(ə)l/
verb

Origin:
Middle English (in the sense 'mingle, mix'): from Old French medler, variant of mesler, based on Latin miscere 'to mix'

Do not confuse medal with meddle. Medal means 'a metal disc given as an award' ( a gold medal), whereas meddle means 'interfere' ( don’t meddle in people’s lives).
