The word "poutier" is spelled using the IPA phonetic transcription as [ˈpaʊ.ti.ər]. This word is derived from the verb "pout," which means to push out one's lips in a sulky or pensive manner. The suffix "-ier" is added to the end to create the comparative form, suggesting that someone who is "poutier" pouts more than someone else. The spelling of this word accurately reflects the pronunciation, with the "ou" representing the diphthong /aʊ/ and the final "-er" pronounced as /i.ər/.
The word "poutier" doesn't have a widely recognized etymology as it is a relatively uncommon term. However, it can be broken down into its base word "pout" and the suffix "-ier".
The term "pout" originated from the Middle English word "pouten" or "putten", which means "to thrust out the lips" or "look sulky or displeased". It is believed to have been derived from the Old English word "putung" or "pytan", meaning "to pout or swell". This Old English word itself might have come from the Proto-Germanic word "putōną".
The suffix "-ier" in "poutier" is derived from the French suffix "-ier", which is used to form an adjective or noun indicating a person or thing related to the base word. It is derived from Latin "-arius".
