There is no such thing as "sitizenship."
However, Citizenship is "the state of being a citizen of a particular social, political, national, or human resource community," according to Wikipedia.
Citizenship is the status of being a member of a specific country, granting individuals certain rights and responsibilities within that nation. It typically involves legal and social membership, entitling individuals to protection under the law, the right to vote, and access to public services. Citizenship can be obtained through birth, naturalization, or descent from citizen parents.
