The spelling of the word "mannes" may seem unconventional to some English speakers. However, it is an archaic form of the word "man's," used to denote possession. The IPA phonetic transcription of "mannes" is /ˈmænɪz/, with the "ae" representing the long "a" sound, and the final "es" indicating the possessive form. This spelling was common in Old English, but has since been replaced by the modern apostrophe-s construction. Nonetheless, "mannes" may still be encountered in some literary or historical contexts.
The word "mannes" is derived from the Old English word "mann", which means "human being" or "person". It can be traced back to the Proto-Germanic word "mannaz" and the Proto-Indo-European root "man-" or "mon-", which generally refers to "thinking" or "intelligence". Over time, "mannes" evolved to become the possessive form of "mann" in Middle English, indicating it belongs to a man.
