IPA: //ˈfɔːrsteɪdʒ//
KK: /ˈfɔrˌsteɪdʒ/
The area of a stage that is located in front of the closed curtain, often used for performances or presentations.
The actors waited in the forestage before the curtain opened for the audience.
Forestage → It is formed from "fore-" (meaning before or in front) and "stage" (from Old French *estage*, meaning a platform or stage). The word "forestage" refers to the part of a stage that is in front or before the main area.
Think of something that is 'in front' ('fore-') of a 'platform' ('stage') — that's why forestage refers to the front part of a stage.
