noun
daughter of a good family; young lady
Kansai dialect honorific term for a young lady from a respectable family. Similar to こいさん but used for a daughter rather than a younger sister.

Derived from the honorific prefix いと (related to いとしい, 'dear') combined with the honorific suffix さん. The exact historical derivation is uncertain.
