The phrase "caught fire" is composed of two words: "caught" and "fire", with each having its own distinct etymology.
1. Caught: The word "caught" is the past participle form of the verb "catch". It originated from the Old English word "cēaht" or "cēahte", which meant "to capture or seize". Over time, it evolved into the Middle English word "cahte", which eventually became "caught" in modern English.
2. Fire: The word "fire" traces its roots back to the Proto-Indo-European language, where the term "péh₂wr̥" referred to heat or fire. This Proto-Indo-European word gave rise to various related terms in different languages. In Old English, the term "fȳr" was used, which eventually became "fire" in modern English.
