What is the definition of "shituki"? This term may be found in Rambam, Mamrim 5:9.
I apologize that I was not able to be more specific in adding contextual 'tags'.
Kiddushin 69a (Art Scroll Kiddushin 69a4), The end of the first mishna chapter 4 Asarah Yochasin. There are ten classes of geneology, this is one of them.
These are shetukim: Anyone who knows the identity of his mother, but does not know the identity of his father 9
Shetuki literally means "the quieted one" (from the root שתק, quiet). [A child without a father is liable to address any adult male as "Father". When he does so], his mother must silence him. (Rashi)
