The spelling of "auto question" can be explained through the use of IPA phonetic transcription. "Auto" is pronounced as /ˈɒ.təʊ/, with the sound of "o" being like in "hot" and "u" being like in "put". "Question" is pronounced as /ˈkwes.tʃən/, with the sound of "qu" being like in "queen".

The term "auto question" does not have a specific etymology as it appears to be a combination of two separate words. "Auto" is a prefix derived from the Greek word "autos", meaning "self". It is commonly used in English to refer to something that is automatic, self-operating, or related to automobiles. "Question", on the other hand, comes from the Latin word "quaestio", which means "inquiry". It refers to the act of asking or seeking information. Therefore, "auto question" could simply be a combination of these two words without a distinct etymology of its own.
