Pure
Catherina is a Latinate elaboration of Catherine, which ultimately derives from the Greek name Aikaterine. While the exact etymology is debated, it has been associated with the Greek word 'katharos' meaning pure since the early Christian era. This specific spelling offers a more melodic, four-syllable alternative to the classic Catherine.
