Paternity is everything to do with being a father. Paternity leave, a paternity test, establish paternity.
Paternity leave is the time a father may take after a birth, and Britain's statutory allowance of two weeks is among the shortest in Europe. A paternity test compares DNA and is close to conclusive. Establishing paternity matters for legal responsibility rather than for feeling. Note maternity, which does the same work on the other side; and paternal, meaning fatherly.
