IPA: /prəˈspɛktər/
KK: /prɑːˈspɛktər/
A person who searches for valuable minerals or oil in a specific area.
The prospector spent months searching the mountains for gold.
Prospector → It is formed from "pro-" (meaning for or in favor of) and "spectare" (meaning to look or to see). A prospector is someone who looks for valuable minerals or resources, particularly in the context of mining.
Think of someone who is 'looking for' ('spectare') something valuable 'for' ('pro-') themselves — that's why a prospector is someone who searches for resources.
