APY – As a person whose parents spoke Ladino but did not pass it down to their children, I highly doubt what you say about Ladino being mamma loshen for anybody younger than the age of 75. Most Sephardim speak the language of the country to which they migrated after the Inquisition – Farsi is much more common than Ladino and I don’t even know if they remember it in the Arab countries. You will also have French, Spanish, and Arabic spoken in Sephardic homes but very little Ladino any more.
147 – “Torah HaKedosho” was written in Loshon HaKodesh. This is NOT the same as Hebrew, which was written by Ben Yehuda.
