"Variant of Yitzhak"
The name Yitzchok is commonly a male name from the "Hebrew" origin.
Yitzchok is a Yiddish spelling of the Hebrew name Yitzhak, which appears in English as Isaac. The Hebrew name is linked in the book of Genesis to the root tsachaq, meaning to laugh, and Jewish naming dictionaries gloss Yitzhak accordingly. The ch in Yitzchok represents the Hebrew letter chet, so the spelling reflects Ashkenazi pronunciation rather than a different name.
Yitzhak means "He will laugh, Laughter, God smiles.".
The pronunciation of Yitzchok is YITS-khok.
