Usage
What does congenital mean? Congenital describes something that is or is related to a condition present from birth or during fetal development. The word congenital can refer to a condition occurring at the time of birth or while the embryo is developing, as in The scientists noticed multiple congenital defects in the kangaroo embryos. Informally, congenital can mean something is so complete that it seems to have been that way since birth, as in Frank is a congenital liar. Congenital can refer to a condition that is either inherited or caused by the environment, however there is an important point to remember. In medicine, the word congenital is a general term to refer to any disease that can be present since birth. However, congenital isn’t used interchangeably with words like genetic or hereditary. This is because not all diseases or disorders that can happen during pregnancy (meaning they are congenital) are caused by genes or inheritance. Congenital is similar to the words innate and inborn, however congenital can refer to pre-birth development and, even in the informal sense, usually refers to negative traits or qualities. Example: The rats’ misshapen feet appear to be a congenital defect that they have had since they were born.
Synonym Usage
See innate.

Etymology
Origin of congenital
First recorded in 1790–1800; from Latin congenit(us) “inborn, innate” ( con- con- + geni-, variant stem of gignere “to give birth” + -tus past participle suffix) + -al 1
Explanation
Congenital refers to something present at birth but not necessarily inherited from the parents. Babies with heart disorders developed in utero can live long and productive lives, in spite of their congenital birth defect. Congenital derives from the Latin genus, to beget. Something that is present at one’s begetting, during fetal development, or at birth is congenital. Fetal alcohol syndrome, which develops in fetuses if their mothers are drinking heavily while pregnant, is a congenital disorder. You might also use congenital to describe something seemingly inborn "a congenital sense of humor," or a "congenital faith."
