[Mesorah] Dikduk question

[Zev Sero]

If one were to turn "God is my miracle" into a name, would it be "Nisiel"
with a chirik under the nun, or "N'siel" with a sh'va under the nun? (Note
that a sh'va would make it sound as if it should be spelt with a sin instead
of a samech, and mean "Prince of God")?

Zev Sero        If they use these guns against us once, at that moment
zev at sero.name   the Oslo Accord will be annulled and the IDF will
                 return to all the places that have been given to them.
