The spelling of the word "in dentures" may seem confusing to those unfamiliar with English pronunciation. The first syllable, "in," is pronounced with the short "ih" sound. The second syllable, "den," contains a vowel sound represented by the letter "e" but pronounced as a short "e" as in "bed." The third syllable, "tures," includes a consonant cluster "tur" and a final "z" sound represented by the letter "s." Therefore, the word is spelled with the IPA transcription /ɪn ˈdɛntʃərz/.
The term "denture" comes from the Latin word "dentulus", which means "small tooth". It entered English in the late 16th century, borrowed from the French word "denture" with the same meaning. "In dentures", on the other hand, appears to be a construction that does not have a specific etymology itself, as it is a combination of the preposition "in", meaning "inside" or "within", and the noun "dentures", referring to the artificial replacements for missing teeth. The phrase "in dentures" is typically used to describe something that is happening or situated within dentures.
