Co-gnatus, ‘born together’ (or ‘descended from the same ancestor’), derives from the Latin verb gigno (earlier geno), meaning ‘beget’ or ‘bring forth’. Its root forms -gn-, -gen- and-gon- have begotten the stems of many English words, along with its complement verb nascor (‘to be born’), through its participial form natus (or gnatus), source of English words such as nature and native.
