_Infant_, also, is a loan-word in English. In Latin, _infans_ was the coinage of some primitive student of children, of some prehistoric anthropologist, who had a clear conception of "infancy" as "the period of inability to speak,"--for _infans_ signifies neither more nor less than "not speaking, unable to speak." The word, like our "childish," assumed also the meanings "child, young, fresh, new, silly," with a diminutive _infantulus_. The Latin word _infans_ has its representatives in French and other Romance languages, and has given rise to _enfanter_, "to give birth to a child," _enfantement_, "labour," two of the few words relating to child-birth in which the child is directly remembered. The history of the words _infantry_, "foot-soldiers," and _Infanta_, "a princess of the blood royal" in Spain (even though she be married), illustrates a curious development of thought. Our word _daughter_, which finds cognates in Teutonic, Slavonic, Armenian, Zend, Sanskrit, and Greek, Skeat would derive from the root _dugh_, "to milk," the "daughter" being primitively the "milker," --the "milkmaid,"--which would remove the term from the list of names for "child" in the proper sense of the word. Kluge, however, with justice perhaps, considers this etymology improbable. A familiar phrase in English is "babes and sucklings," the last term of which, cognate with German _Säugling_, meets with analogues far and wide among the peoples of the earth. The Latin words for children in relation to their parents are _filius_ (diminutive _filiolus_), "son," and _filia_ (diminutive _filiola_), "daughter," which have a long list of descendants in the modern Neo-Latin or Romance languages,--French _fils, fille, filleul_, etc.; Italian _figlio, figlia_, etc. According to Skeat, _filius_ signified originally "infant," perhaps "suckling," from _felare_, "to suck," the radical of which, _fe_ (Indo-European _dhe_), appears also in _femina_, "woman," and _femella_, "female," the "sucklers" _par excellence_. In Greek the cognate words are [Greek: _titthae_], "nurse," _thaelus_, "female," _thaelae_, "teat," etc.; in Lithuanian, _dels_, "son." With _nonagan_, "teat, breast," are cognate in the Delaware Indian language _nonoshellaan_, "to suckle," _nonetschik_, "suckling," and other primitive tongues have similar series.
