IPA: //ˈsʌbˌsɛntər//
KK: /sʌbˈsɛntər/
A smaller center that is not the main one, often used for shopping or other activities, located away from the main business area of a city.
The new subcenter has several shops and restaurants that attract local residents.
Subcenter → It is formed from "sub-" (meaning under or below) and "center" (from Latin "centrum", meaning the middle point). The word "subcenter" refers to a point that is located beneath or secondary to a main center.
Think of something that is located 'under' ('sub-') the main 'middle point' ('center') — that's why a subcenter is a secondary point beneath the main one.
