cognomen. a latin word, which signifies a family name. the praenomen among 
the romans distinguished the person, the nomen, the gens, or all the kindred 
descended from a remote common stock through males, while the cognomen 
denoted the particular family. the agnomen was added on account of some 
particular event, as a further distinction. thus, in the designation publius 
cornelius scipio africanus, publius is the proenomen, cornelius is the 
nomen, scipio the cognomen, and africanus the agnomen. vicat. these several 
terms occur frequently in the roman laws. see cas. temp. hardw. 286; 1 tayl. 
148. see name; surname.
