The correct spelling of the phrase "doeth takeoff of" is "doth takeoff of." The word "doth" is an archaic form of "does" and is pronounced /dʌθ/. It's commonly found in old English literature and poetry. "Takeoff" refers to the upward movement of an aircraft during departure and is pronounced /ˈteɪkɒf/. The combination of the two words implies that something or someone is departing or taking flight. It's important to correctly spell words to ensure clear communication and avoid confusion.
