Ottava

The name Ottava is directly derived from the Latin word 'octava', meaning 'eighth'. It is most commonly associated with musical terminology, where an 'ottava' (or 'octave' in English) refers to an interval of eight notes. As a given name, it is quite rare and likely originated as a descriptive name for an eighth-born child, or perhaps with a symbolic connection to music or the number eight.

Its usage as a personal name is not widespread and does not have a deep historical lineage like many other names. It appears to be a more modern or niche choice, possibly appealing to parents with a connection to music or a fondness for unique, numerically-derived names. The feminine ending '-a' is typical for Latin-derived names in many Romance languages.
