Murvyn is a unique name that doesn't follow conventional spelling rules. It is pronounced as "mər-vin" with the schwa sound "ə" in the first syllable. The "y" at the end modifies the vowel sound to be a short "i" in the second syllable, as in "bin" or "fin." The "v" and "y" may have been added to differentiate the name from the more common spelling of Marvin. While unconventional spellings can be confusing, they can also give a name personality and make it stand out.
