Gracious
Ivann is a variant of Ivan, which is the Slavic form of the Greek name Ioannes (John). It ultimately derives from the Hebrew name Yochanan, signifying that God has been gracious. The double 'n' spelling is a modern stylistic variation that adds a unique visual flair to the traditional Slavic classic.
