IPA: /dɪsˈɪn.tɪ.ɡreɪ.tər/
KK: /dɪsˈɪntɪɡreɪtər/
A device or person that breaks something into smaller parts or pieces.
The scientist used a disintegrator to break down the material for analysis.
Disintegrator → It is formed from "dis-" (meaning apart) and "integrate" (from Latin "integrāre", meaning to make whole). The suffix "-or" (meaning one who) indicates a person or thing that performs an action. Thus, a disintegrator is something that causes something to come apart or lose its wholeness.
Think of something that makes things come 'apart' ('dis-') and breaks them down from being 'whole' ('integrate'). This helps you remember that a disintegrator is something that breaks things down.
