The word "mirman" is spelled with the letters 'm', 'i', 'r', 'm', 'a', and 'n'. It is pronounced as /ˈmɪrmən/. In IPA phonetic transcription, the stresses are on the first and third syllables. The 'm' sound is repeated twice to indicate two separate syllables. The 'i' is pronounced as a short vowel sound, like in "sit". The 'r' is pronounced with a tap or a flap. The 'a' is pronounced as a short a sound, like in "cat", and 'n' is pronounced with a soft n sound.
Based on my research, there doesn't appear to be a widely accepted etymology for the word "mirman". It is possible that it might be a surname or a proper noun deriving from personal names. However, without any specific context or additional information, it is challenging to provide a precise origin for this word.
