IPA: /ˈɡʌʃər/
KK: /ˈgʌʃər/
A person or thing that gushes, often referring to a well that produces a large amount of oil or gas.
The new oil gusher in the field has increased production significantly.
Gusher → The word originates from the verb 'gush' (from Middle English *gussen*, meaning to flow out suddenly) combined with the suffix '-er' (meaning a person or thing that performs an action). A gusher is something that flows out suddenly, often used to describe a well that produces oil or water in a large quantity.
Think of something that 'flows out suddenly' — that's what a gusher does, and the '-er' indicates it's the source of that flow.
