Correct spelling for the English word "more stenchful" is [mˈɔː stˈɛnt͡ʃfə͡l], [mˈɔː stˈɛntʃfəl], [m_ˈɔː s_t_ˈɛ_n_tʃ_f_əl] (IPA phonetic alphabet).
The word "more stenchful" does not have a specific etymology as it is a combination of two English words: "more" and "stenchful".
"More" is derived from the Old English word "māra" which means "greater" or "additional". It has remained relatively unchanged phonetically and semantically throughout the history of the English language.
"Stenchful" is formed by adding the suffix "-ful" to the noun "stench". "Stench" originates from the Old English word "stenc" or "stenċ" which referred to a strong, foul odor. By attaching the suffix "-ful", meaning "full of" or "characterized by", we get "stenchful", which can be understood as "full of stench" or "having a strong odor".
