IPA: /rɪˈtrɛnʧmənt/
KK: /rɪˈtrɛnʧmənt/
A reduction in spending or expenses, often made to save money or improve financial stability.
The company announced a retrenchment to cut costs and improve its financial situation.
Retrenchment is formed from "re-" (meaning back or again) and "trencher" (from Old French *trencher*, meaning to cut). The word refers to the act of cutting back or reducing expenses or resources.
Think of going 'back' ('re-') to 'cut' ('trencher') something down — that's why retrenchment means cutting back.
