In civil law
One who had no property to be taxed, and paid a tax only on account of his children (proles); a person of mean or common extraction. The word has become Frenchified, proletaire signifying one of the common people. PROLICIDE (Lat. proles, offspring, cedere, to kill). In medical jurisprudence. A word used to designate the destruction of the human offspring. Jurists divide the subject into "foeticide," or the destruction of the foetus in utero, and "infanticide," or the destruction of the new-born infant.
