One theory of the Etymology of Ithmia is derived from the Noro-Ithmic expression "Yîth miô" meaning "We found it" roughly translating into "Eureka". Another theory of the etymology of Ithmia is from the Greek: ἰχθύς, ikhthus, meaning fish, which refers to the large fishing industry that takes up most of it's economy, and also the geographical location.
