Myselven is not a proper word. However, if we break it down phonetically into its individual sounds, we could analyze how it could be spelled. The pronunciation of the first syllable "my" is /maɪ/ and the second syllable "selven" is /ˈsɛlvən/. Therefore, a possible spelling could be "myselvin" or "myselvene". Nonetheless, it is worth noting that the spelling of a word should always correspond to its meaning, and in this case, "myselven" does not hold any meaning.
