Pronunciation: [wˈɒn sˈe͡ɪm] (IPA) 
The spelling of the phrase "one same" may cause confusion, but it is simply a combination of two single words. "One" is spelled as /wʌn/ in IPA phonetic transcription, meaning there is a short vowel sound followed by the consonant 'n'. "Same" is spelled as /seɪm/, with a long vowel sound followed by the consonant 'm'. Together, "one same" is pronounced as /wʌn seɪm/ and refers to the idea of something being identical or unchanged.
One same refers to something that is identical or exactly the same as another. It implies that two or more items or individuals bear no differences or variations and are absolutely identical in every aspect. The term "one same" denotes a complete similarity or an exact correspondence between different entities. It emphasizes the absence of any distinction, dissimilarity, or divergence between the items or individuals being compared.
The concept of "one same" can be applied to various contexts, such as objects, ideas, or people. For example, if two objects are described as "one same," it means that they look, function, and perform in exactly the same manner without any differentiation. Similarly, if two persons are referred to as "one same," it signifies that they possess identical attributes, characteristics, or qualities, leaving no room for differentiation between them.
The term "one same" exemplifies a state of unity, uniformity, or indistinguishability between multiple entities. It implies that there is no disparity or discrepancy to be found, and any attempt to observe or analyze differences would be futile. Whether used in scientific, philosophical, or colloquial contexts, "one same" emphasizes the absolute equivalence or similarity between entities, underscoring their inseparability and interchangeability.
The etymology of the phrase "one same" can be understood by examining the individual words that make up the phrase.
"Same" originates from the Old Norse word "sami", which means "same" or "unvarying". This word eventually influenced the Old English word "same", which carried the same meaning.
Meanwhile, "one" comes from the Old English word "ān", which refers to the number one or "a single thing".
When combined, "one same" describes something that is identical or unchanged. The specific etymology of this phrase can be traced back to the blending of Old Norse and Old English.
