IPA: /ˈmɪntiər/
KK: /ˈmɪntiər/
Having a stronger or more intense flavor or smell of mint than something else.
The new gum is mintier than the previous flavor.
The word 'mintier' is derived from 'mint' (from Old French *menthe*, meaning the aromatic herb) and the suffix '-ier' (meaning one who or that which). Thus, 'mintier' refers to something that has more of the qualities of mint, particularly its flavor or aroma.
Think of the aromatic herb 'mint' and remember that 'mintier' means having more of that minty flavor or scent.
