The correct spelling of the word is "utmosts" (ʌtmoʊsts). The spelling "utter mosts" is a common misspelling due to the similarity in sound. "Utmosts" means the highest or greatest degree, extent, or intensity. It is important to use correct spelling in written communication to avoid confusion and misunderstandings. Using IPA phonetic transcription, "utmosts" is pronounced as "uh t-mohsts" with the stress on the second syllable.
The term "uttermost" is derived from two separate words: "utter" and "most".
The word "utter" can be traced back to the Old English word "ūtera", meaning "outer" or "external". It later evolved to "uttemest", meaning "outermost" or "farthest". Over time, "uttemest" was simplified to "utter".
The word "most" comes from the Old English word "mǣst", which means "greatest", "largest", or "most". It has remained relatively unchanged throughout its history.
When these two words are combined, "uttermost" refers to the furthest or greatest point, extent, or degree. The term is often used to emphasize the extreme or utmost nature of something.
