Borescope → It is formed from "bore" (from the Old English "borian", meaning to drill or pierce) and "scope" (from Greek "skopein", meaning to look or examine). The word "borescope" refers to an instrument used to look inside a bore or hole, typically for inspection purposes.
Think of 'boring' a hole ('bore') and then using a tool to 'look' inside it ('scope'). This helps you remember that a borescope is used to examine the inside of a drilled hole.
