Etymology
Origin of impregnate
First recorded in 1535–45; from Late Latin impraegnātus, past participle of impraegnāre “to fertilize, impregnate,” equivalent to im- im- 1 ( def. ) + praegn-, stem of praegnās, variant of praegnāns (stem praegnant-) “pregnant, with child” + -ātus past participle suffix; see origin at pregnant 1 ( def. ), -ate 1 ( def. )
Explanation
Use the verb impregnate to describe what happens when a male of any animal species makes a female pregnant. Human fathers impregnate mothers — otherwise, they would not become fathers. When dog breeders mate two German shepherds, they hope that the male will impregnate the female, or make her pregnant. When your cat has kittens, it's because the neighbor's cat impregnated her several months earlier. The Latin root, impraegnare, comes from in, "into," and praegnare, "pregnant."
