IPA: /kəˈmɪn.juː.ʃən/
KK: /kəˈmɪn.juː.ʃən/
The process of breaking or grinding something into smaller pieces or particles.
The comminution of the rock made it easier to extract the minerals.
Comminution is formed from "com-" (meaning together) and "minutio" (from "minuere", meaning to lessen or reduce). The word describes the process of reducing something into smaller parts or particles, effectively breaking it down together.
Think of 'together' ('com-') and 'reducing' ('minutio') something into smaller pieces — that's what comminution means.
